Answer:
Explanation:
The rule for an isosceles triangle is that the triangle must have two sides of equal length. These two sides are called the legs of the triangle and the unequal side is called the base. The isosceles triangle theorem further states that the angles opposite to each of the equal sides must also be equal.A triangle is a two-dimensional geometric shape that is made up of three line segments that are connected to each other at their endpoints (called vertices), which results in a closed shape that has three sides, three vertices, and three angles. Triangle RST shown contains the vertices R, S, and T and the angles
Triangle RST
A triangle is a 2-D shape with three sides, three corners, and three angles.
An important property of triangles is that the sum of all of the angles of a triangle must equal 180 degrees.
The angles of a triangle can be any of the following:
A right angle, which is an angle with a measure of exactly 90 degrees.
An acute angle, which is an angle with a measure that is less than 90 degrees.
An obtuse angle, which is an angle with a measure that is greater than 90 degrees.
The isosceles triangle definition states that an isosceles triangle is a special kind of triangle that has at least two sides that are equal in length. The word isosceles comes from the prefix isos, which means equal, and the suffix skeles, which means legs. In the isosceles triangle LMN shown, sides LM and LN are equal in length, while side MN is different. The term congruent is used to describe the two sides of an isosceles triangle that are equal in length. In general, congruent simply means equal in shape and size.
