Triangle Congruence Review
The two triangles below are congruent. Select the congruence shortcut that proves it.
Try again. We know that the triangles
share a side so one side is congruent,
but we can’t determine if either of the
other sides are congruent.
Try again. We know that the triangles

but we can’t determine if either of the
other sides are congruent.
YES! Since these triangles share a
side, we can say that those two sides
are congruent.
Try Again. Although all three angles
are congruent, AAA doesn’t not prove
triangle congruency.

Triangle Congruence Review
The two triangles below are congruent. Select the congruence shortcut that proves it.
Try again. We cannot determine if the
3rd sides of the triangles are congruent
with the information that is given.
YES! The vertex that the two triangles
share creates vertical angles. Vertical
angles are congruent angles.
Try again. We can determine one set
of angles that are congruent (Vertical
Angles), but we cannot determine if
any other set of angles
Are congruent.
Try Again. There are two sets of sides
and one set of angles that are
congruent, but the angle is IN
BETWEEN the sides.

The two triangles below are congruent. Select the congruence shortcut that proves it.
*The horizontal lines are parallel*
Try again. We know that one set of
the sides in the triangles are
congruent, but we cannot determine if
either of the other sides are congruent.
Try again. We know that one set of the
sides in the triangles are congruent, but we
cannot determine if either of the other
sides are congruent.
YES! Because the two horizontal lines
are parallel we know that the sets of
base angles are congruent by Alternate
Interior Angles.
Try Again. Although all three angles
are congruent, AAA doesn’t not prove
triangle congruency.
