Marcus drew a line from point y to point w in the rectangle shown below. he created two identical triangles. classfy the triangles by size of their angles and by the lengths of their sides.

When you draw a diagonal line from Y to W, you will create two congruent triangles.

Each of these triangles will have three sides of different lengths, making them scalene triangles.

In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.

Both triangles are right, scalene triangles.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
