Two Isosceles Triangles that are both acute triangles.
The sum of the measures of the internal angles of a triangle is 180°
Condition: Given 50° as the measure of an angle of the isosceles triangle, there are two possible isosceles triangles that can be drawn.
a) First Triangle is an Isosceles triangle with 50° as a base angle. The measurements of the internal angles are: 50° - 80° - 50°.
b) Second Triangle is an isosceles triangle with 50° as the measurement of the angle opposite the base segment of the triangle. The measurements of the internal angles are 65° - 50° - 65°
