### Congruence and triangles date_____ period____ complete each congruence statement by naming the corresponding angle or side.

Write triangle congruence statement. Play this game to review mathematics. In similar shapes, the sides are in proportion. Suppose line gh ≅ jk, line hi≅kl and ∠i≅∠l.

This concept teaches students how to write congruence statements and use congruence statements to determine the corresponding parts of triangles. The ‘~’ sign is a congruence sign in geometry. To write a correct congruence statement, the implied order must be the correct one.

1) d abc @ 2) d uvw @ 3) d pqr @ 4) d klm @ 5) d def @ 6) d tuv @ 7) d def d str d xyz d jkl @ d nml For example, a congruence between two triangles, abc and def, means that the three sides and the three angles of both triangles are congruent. Sss and sas write which of the sss or sas postulates if either can be used to prove the triangles congruent.

Describe a transformation that can be performed on abc that will result in a triangle in the third quadrant. If , what else do you know? Write the statement and then under the reason column, simply write given.

Comparing one triangle with another for congruence, they use three postulates. You can start the proof with all of the givens or add them in as they make sense within the proof. Also, learn about congruent figures here.

Although congruence statements are often used to compare triangles, they are also used for lines, circles and other polygons. Which congruence statement can you write about the triangles int eh previous problem? Write down what you are trying to prove as well.
