Question

Finding Angle Sums A diagonal is drawn on a square. How many triangles are formed? What is the sum of the measures of the angles of a triangle? ° What is the sum of the angle measures of the square? °

Answer 1

It's 2 , 180 , and 360.

Answer 2

When a diagonal s drawn on a square, the two triangles that are created will each have angles with a sum of 180 degrees.  This is true of all triangles.  The sum of the angles in the original square is 360 degrees.  This is always the sum of the angles on any quadrilateral.
