It is an isosceles triangle
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
An isosceles triangle has two equal angles.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
congruent/equivalent in measure
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
The three interior angles measure 45, 45 and 90 degrees.
An equilateral triangle is a triangle with all sides & angles having the same measure.An isosceles triangle is a triangle with 2 sides & angles measuring the same, leaving one angle/side to be different.A scalene triangle is a triangle with no sides and/or angles measuring the same length.
An isosceles triangle because its base angles are equal in size
The base angles of an isosceles triangle are congruent.
