A triangle drawn under the condition of two sides and a non-included angle, where the angle is acute, does not determine a unique triangle. This condition determines two non-identical triangles.

correspondence; three side lengths of a **triangle determine a unique triangle**. ? Students understand that two **triangles** are identical if two corresponding sides and the included angle are. equal under some correspondence; two sides and an included angle of a **triangle determine a unique triangle**.

is SSS a unique triangle? **SSS** (side, side, side) **SSS** stands for “side, side, side” and means that we have two **triangles** with all three sides equal. If three sides of one **triangle** are equal to three sides of another **triangle**, the **triangles** are congruent.

One may also ask, what is a non unique triangle?

A **triangle** drawn under the condition of two sides and a **non**-included angle is often thought of as a condition that does not determine a **unique triangle**. Furthermore, there is a maximum of two possible **non**-identical **triangles** that can be drawn under this sub-condition.

What is a unique polygon?

The **Unique Polygon** Theorem is: All regular **polygons** with the same number of sides are similar.

### Is AAA a unique triangle?

Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. We said if you know that 3 sides of one triangle are congruent to 3 sides of another triangle, they have to be congruent.

### What makes a triangle impossible?

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. In other words, as soon as you know that the sum of 2 sides is less than (or equal to) the measure of a third side, then you know that the sides do not make up a triangle.

### What is a more than one triangle?

A unique triangle means there is ONLY ONE WAY to create the triangle. There are certain criteria that must be met in order for more than one triangle to be made with the same given information…

### How many unique triangles can make?

Answer: 15 unique triangles can be made. Step-by-step explanation: Given : A triangle has one angle measures 60° and another angle is an obtuse angle .

### Is an equilateral triangle a unique triangle?

Equilateral Triangle. A triangle which has all three of its sides equal in length. An equilateral triangle is one in which all three sides are congruent (same length). Because it also has the property that all three interior angles are equal, it really the same thing as an equiangular triangle.

### Is an isosceles triangle unique?

Isosceles triangles are special and because of that there are unique relationships that involve their internal line segments. Theorem 34: If two angles of a triangle are equal, then the sides opposite these angles are also equal. Theorem 35: If a triangle is equiangular, then it is also equilateral.

### What is a no triangle?

Types of Triangle For example, a scalene triangle (no sides the same length) can have one interior angle 90°, making it also a right triangle. This would be called a “right scalene triangle”.

### How do you know if you can make more than one triangle?

In general, a unique triangle may always be drawn if three side lengths are given and the sum of any two is greater than the third. c) More than one triangle can be drawn with Angle A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

### Does an acute triangle have 3 acute angles?

Acute triangle. A triangle where all three internal angles are acute (less than 90 degrees). In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: Less than 90° – all three angles are acute and so the triangle is acute.

### Can a triangle be formed with three sides of equal length?

Can three equal side lengths form a triangle? Yes. It’s called an equilateral triangle, and it can work because two side lengths added together are bigger than the third side.

### What does isosceles triangle mean?

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

### What is the least number of measures needed to construct a triangle?

3

### Can you construct a triangle with the given side lengths?

No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. ANSWER: No; No; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
