## Spectrum Math Grade 6 Chapter 6 Lesson 6.9 Graphing Polygons: Right Triangles Answers Key

Triangle problems can also be solved through graphing on the coordinate plane.

If points A (4, 8) and 8 (-8, -3) are vertices of the hypotenuse (longest side) of a right triangle, where does vertex C fall?

Connect the vertices and then draw lines straight from points A and 8 to find where vertex C will fall.

Point C can occur at point (-8, 8) or point (4, -3).

**Use the coordinate grids to find the missing vertex of each polygon.**

Question 1.

a right triangle with points at (3, 2) and (-5, 6)

The missing point is at ____ or _____.

Answer:

Let us assume the given points (3, 2) and (-5, 6) as A and B respectively.

If points A (3, 2) and B (-5, 6) are vertices of the hypotenuse of a right triangle.

Connect the vertices and then draw lines straight from points A and B.

The intersecting points will be the missing point.

Point C can be (-5,6) or (3,6)

Question 2.

a right triangle with points at (-4, -6) and (5, 2)

The missing point is at ____ or _____.

Answer:

Let us assume the given points (-4, -6) and (5, 2) as A and B respectively.

If points A (-4, -6) and B (5, 2) are vertices of the hypotenuse of a right triangle.

Connect the vertices and then draw lines straight from points A and B.

The intersecting points will be the missing point.

Point C can be (-4,2) or (5,-6)
