Aright triangle has a vertex at point a, a height of 4 units, and a base of 5 units.

use the polygon tool to draw the triangle.

each segment on the grid represents 1 unit.

The triangle is shown in the below diagram.

Step-by-step explanation:

It is given that each segment on the grid represents 1 unit and point A is a vertex of a right angle triangle.

The height of triangle is 4 units, and the base is 5 units.

Let the coordinates of A be (x,y).

There are many possibilities to draw a right angled triangle having height 4, base 5 and vertex at A.

The height of the triangle is 4 units, so the coordinate of another vertex B is (x,y+4).

The base of the triangle is 5 units, so the coordinate of another vertex C is (x+5,y).

The triangle is shown in the below diagram.

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
