Jason wants to prove triangle ABC congruent to triangle XYZ. He knows that AB = XY and AC = XZ. What other information must he know to prove the triangles congruent?
Jimmy knows that in triangles MST and RLK, MS = RL, ST = LK, and MT = RK. Which postulate or theorem can he use to prove the triangles congruent?
Which of the following postulates and theorems does not exist?
Jackson knows that in triangles ABC and DEF, AB = DE, angle B is congruent to angle E, and angle C is congruent to angle F. Is he able to prove the triangles congruent? If so, how?
Kathy knows that in triangles FGH and WXY, FG = WX, angle G is congruent to angle X, GH = XY. Can she prove the triangles congruent? If so, how?
Sam knows that in triangles MTO and LKR, MT = LK, MO = LR, and angle O is congruent to angle R. Can he prove the triangles congruent? If so, how?
Which of the following postulates and theorems can be used to prove two right triangles congruent?
In triangle ABC, AB = AC. If the measure of angle B = 80 degrees, find the measure of angle A.
In triangle DEF, angle D is congruent to angle F. If DE = 5 and EF = 7, find DF.
In triangle MNO, OM = NO. Name the vertex angle.
True or False: If the three angles of one triangle are congruent to the three angles of another triangle, then the three sides of the first triangle are congruent to the three sides of the second.
In triangle ABC, the
_______ of vertex A is the segment from vertex A to the midpoint of segment BC.
In triangle DEF, the
_______ of vertex E is the segment from vertex E to the perpendicular of segment DF.
