A triangle has two equal sides. a)
What is the special name for this type of triangle?
b)
One of the angles in this triangle measures 100°.
What is the size of each of the other two angles?
+

A. isosceles triangle

B. each two angles equal 40°

Step-by-step explanation:

A. the special name for this type of triangle is isosceles triangle.

As isosceles triangles are the triangles whose base angels are equal and the Two sides are equal.

B.

given

one angle = 100°

As it is isosceles triangle so two angles are equal. So let the angle be x

Then

x + x + 100° = 180° [sum of angles of triangle ]

2x = 180° - 100°

2x = 80°

2x = 80°

x = 40°
