For top: select a, b, c, or d. Select: ACB or CBA, Select: CB or AB, Select: equilateral or isosceles. For bottom: Select: Symmetric Property, reflective property, transitive property or definition. Select: SSS, ASA, SAS, or AAA. Select Use a straightedge. Draw a line. Draw an acute angle with vertex A along the line. Then use a compass to copy the angle. Place the compass point at another point B along the line and draw the copied angle so that the angle faces the original angle. Label the intersection of the angle sides as point C. Select the triangle you have formed. What is true about the two base angles of A A B C? What do you know about CA and CB ? What kind of triangle did you form? Complete the explanation. B B C D B B ZCAB = (select) w, so opposite sides CA and (select) are congruent. Therefore, it is an (select) triangle. Prove the Isosceles Triangle Theorem as a paragraph proof. Given: A B = AC Prove: 2B = 20 It is given that AB = AC. Through the (select) of Congruence, it is understood that ZA = ZA. Given that BA = CA, then AABC = ACB by the (select) w|Triangle Congruence Theorem. Therefore, 2B ~ (select)v because corresponding parts of congruent triangles are congruent
