Carla drew two triangles; triangle ABC and triangle PQR, on a grid. She planned to cut out the two triangles to make a flag. The vertices of triangle ABC are at A(1, 4), B(-2, -1), and C(3, -2). The vertices of triangle PQR are at P(-3, 0), Q(-2, -4), and R(2, 3). Using the coordinates of the vertices of each triangle explain whether the two triangles are congruent, similar or neither. Note: I understand I have to apply the formula, but I don't know what goes into it. Help is appreciated.

    what i think is.... findthe lengths of each sides of the 2 triangles .. and then compare the two triangles!!

    Yes, I do, but I was wondering if the two triangles were congruent, similiar, or neither? It looks like neither.

    When you get the distance, you can compare them Same length of side pairs=> congruent Length are in ratio => similar Neither => neither

    \[AB=\sqrt{(1-(-2))^2 + (4-(-1))^2} = \sqrt{(3)^2 + (5)^2} = \sqrt{34}\]

    The vertices of triangle PQR on a coordinate grid are P(1, 5), Q(1, 3), and R(3, 2). Provide the coordinates of the vertices A, B, and C of triangle ABC that is congruent to PQR and explain why the two triangles are congruent. Do you understand this?

    I don't know what it is asking for. If the two triangles are congruent, they equal each other.

    see.. if two triangles ar congruent means .. there all sides are equal.. and allangles are equal!!
