5.3 The Isosceles Triangle Theorems
... Plan for proof: You can show that AB and AC are corresponding parts of congruent triangles. Draw the bisector of —A as your auxiliary line, show that —ADB @ —ADC (remember that if two angles of one triangle are congruent to two angles of another triangle then the third angles are congruent), and the ...

... Exterior angle of a polygon: an angle that forms a linear pair with one of the angles of the polygon. Remote interior angles of a triangle: the two angles non-adjacent to the exterior angle. Measure of the exterior angle of a triangle: equals the sum of the measures of the two remote interior angles ...

... A Square is a rectangle, so the same properties for rectangles apply to it, plus these: All four sides have the same length. Each diagonal divides the square into two 45o-45o-90o right triangles. The diagonals are perpendicular to each other. A Trapezoid is a quadrilateral in which one pair of side ...
