Answer:
The base angles of an isosceles triangle are the angles formed by the base and one leg of the triangle. The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base.
Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. Congruent polygons necessarily have to have the same shape and the same size.
Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal. We can tell whether two triangles are congruent without testing all the sides and all the angles of the two triangles.
corollary is a proposition that follows from (and is often appended to) one already proved.
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
Legs of a Right Triangle. The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse. Sometimes it is required to solve a right triangle to find the length of one or both of the legs of the right triangle.
The equal sides of an isosceles triangle are known as the 'legs.' The third and unequal side of an isosceles triangle is known as the 'base. The angles situated opposite to the equal sides of an isosceles triangle are always equal.
Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus, 65 is the base angle and 50 is the vertex angle.
