What are the sides of an isosceles triangle?

In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles. The vertex opposite the base is called the apex.

What is the 3 angles of triangle?

So, the three angles of a triangle are 30°, 60° and 90°.

What angles are in an isosceles triangle?

An isosceles triangle is a type of triangle that has two sides that are the same length. The two marked sides are both the same length. The two angles opposite these two marked sides are also the same: both angles are 70°. All three interior angles add to 180° because it is a triangle.

How do you find the length of a right isosceles triangle?

Consider a triangle with two sides that both have a length of 5 feet, which meet at a 90 degree angle. Since the triangle has a 90 degree angle, we have a right triangle. Since the two shorter sides of the right triangle are the same length, we have a right isosceles triangle.

Which creates two smaller isosceles triangles?

The perpendicular bisector of creates two smaller isosceles triangles. a. Angle Y is a right angle. b. The measure of angle Z is 45°. e. The perpendicular bisector of creates two smaller isosceles triangles. Let x represent the measures of base angles X and Z. Then 2x is the measure of vertex angle Y, and the sum of angles is

What is true about triangle XYZ?

Triangle XYZ is isosceles. The measure of the vertex angle, Y, is twice the measure of a base angle. What is true about triangle XYZ? Select three options. a. Angle Y is a right angle. b. The measure of angle Z is 45°. c. The measure of angle X is 36°. d. The measure of the vertex angle is 72°. e.

Can an isosceles triangle be scalene?

In general, an isosceles triangle cannot be scalene. In addition, any equilateral triangle is also not scalene, since all of the sides would have the same length. This right isosceles triangle has angles 45, 45, and 90 degrees. It is not scalene, since two sides have the same length of 5.
