Ab and bc are tangents to the circle. Use the distance formula to find the lengths of bc and gh. And c are points on a circle, centre o. If we are able to show that the three corresponding sides are congruent, then we have enough information to prove that the two triangles are congruent because of the sss postulate! Web this selection of lessons and worksheets help students learn how to prove that two triangles are congruent.
Name the postulate, if possible, that makes the triangles congruent. This rule states that if three sides of one triangle are equal to three sides of another triangle, then both triangles are congruent. Because ab = 5 in triangle abc and fg = 5 in triangle fgh, ab ≅ fg. Web get your free congruent triangles worksheet of 20+ questions and answers.
