Question

Given the points: O (0,0), A(0,4), B (3,0), C(-4,0), and D (0,y). Find two values of y so that ΔOBA ≅ ΔODC. (Hint: make sure you draw a picture) List them in order from smallest to largest.

Answer 1

Answer: -3 and 3

Step-by-step explanation: You first find the area of OBA which is 6, then you plot points that make a triangle that is congurent to 6. I fond that since there was a length of 4 in both, I simply went up three on the y-axis and down three on the y-axis. Sorry for the bad explanation but this is all I knew.
