move constant to the left by adding its opposite to both sides. the sum of the two =0
Answer:
Yes they are
Step-by-step explanation:
In the triangle JKL, the sides can be calculated as following:
- J(2;5); K(1;1)
=> JK =
- J(2;5); L(5;2)
=> JL =
- K(1;1); L(5;2)
=> KL =
In the triangle QNP, the sides can be calculate as following:
- Q(-4;4); N(-3;0)
=> QN =
- Q (-4;4); P(-7;1)
=> QP =
- N(-3;0); P(-7;1)
=> NP =
It can be seen that QPN and JKL have: JK = QN; JL = QP; KL = NP
=> They are congruent triangles
