Here are 3 tips to help you solve geometry problems involving shapes:

(1) Understand the definitions of the shapes your questions ask you about. To help understand the definitions of the many shapes with fancy names, make flash cards with drawings of the shapes and study these cards 5 to 15 minutes at a time a few days in a row until you understand and remember the definitions of the shapes.

(2) If you are dealing with two congruent (= same exact shape, angles, & size) or similar (same shape and angles, but different size with sides of shape A proportional to the sides of shape B) shapes and the questions seems very difficult, try re-drawing one of the shapes carefully so that the angles of the two different shapes that are equal to one another are in the same orientation, and then try again to solve the problem. Make sure that the sides of the two shapes that are proportional to one another are also oriented similarly.

(3) To find out if two triangles are congruent, remember to use the Side-Side-Side, Side-Angle-Side, or Angle-Side-Angle tests.
