## How do you find the scalene isosceles or equilateral?

If none of the sides of a triangle are equal (of equal length), the triangle is scalene. If two or more of the triangles sides are equal, the triangle is isosceles. If all three of the sides of a triangle are equal, it is equilateral. All equilateral triangles are also isosceles, by definition.

What is an isosceles scalene equilateral?

Equilateral: “equal”-lateral (lateral means side) so they have all equal sides. Isosceles: means “equal legs”, and we have two legs, right? Also iSOSceles has two equal “Sides” joined by an “Odd” side. Scalene: means “uneven” or “odd”, so no equal sides.

How do you identify an equilateral?

Equilateral Triangle: A triangle is said to be equilateral triangle if all the sides are equal. If X, Y, Z are three sides of the triangle. Then, the triangle is equilateral only if X = Y = Z. Isosceles Triangle: A triangle is said to be an isosceles triangle if any of its two sides are equal.

### Which of the following triangles have the same side lengths a scalene B isosceles C equilateral D none of these?

Equilateral triangles have the same side length.

What is the shape of the triangle PQR a scalene triangle B isosceles triangle C equilateral triangle D right-angled triangle?

(c) PQR such that PQ = QR = PR = 5cm will have all its sides of equal lengths. Hence, it will be an equilateral triangle. (d) DEF with D = 90 degrees will have one right angle inside the triangle. Hence, it will be a right-angled triangle.

What is a triangle with 3 equal sides called?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

## What is AAA rule math?

AA (or AAA) or Angle-Angle Similarity If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.
