the side opposite the right angle

Theorem 6-6
LL Theorem
If 2 legs of 1 right triangle are
congruent to the corresponding
legs of another right triangle, then
the triangles are congruent
1
Theorem 6-7
HA Theorem
If the hypotenuse and an acute
angle of 1 right triangle are
congruent to the hypotenuse and
corresponding acute angle of
another right triangle, then the
triangles are congruent
Theorem 6-8
LA Theorem
If one leg and an acute angle of 1
right triangle are congruent to the
corresponding leg and angle of
another right triangle, then the
triangles are congruent

Theorem 6-1
HL Theorem
If the hypotenuse and an leg of 1
right triangle are congruent to the
hypotenuse and corresponding leg
of another right triangle, then the
triangles are congruent
Determine whether each pair of right triangles is congruent by LL, HA,
LA or HL and write a congruence statement. If it is not possible to
prove that they are congruent, write not possible.
