The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
Theorems include: measures of interior angles of a triangle sum to 180Â°; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point. The student will: x prove that the sum of the measures of the interior angles of any triangle is 180 degrees. x prove that the base angles of an isosceles triangle are congruent. x prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side and half the length of the third side. x prove that the medians of a triangle meet at a point. x use theorems about triangles to prove claims about geometric figures .
