Lessons

Explain why $\triangle ABD$ $\cong$ $\triangle CDB$ .
Decide and explain if $\triangle LMP$ $△ L MP$ $\cong$ $≅$ $\triangle XYZ$ $△ X Y Z$ using the following coordinates.
1. L(1, 1), M(3, 4), P(5, 1), X(-5, -4), Y(-3, -1), Z(-1, -4)
2. L(2, -2), M(6, -1), P(2, 6), X(-2, -2), Y(2, -1), Z(0, -5)
3. L(1, -1), M(-1, 4), P(5, 4), X(2, 6), Y(5, 12), Z(5,6)
