100 points and brainliest if answered correctly, prove that the sum of the measures of the interior angles of a triangle is 180°. be sure to create and name the appropriate geometric figures

Remember that a triangle is 1/2 of a square. A square has 4 interior angles, which are all exactly 90 degrees (if they were not all 90 degrees, it would not be a square). 90 x 4 = 360. So if a square / 2 = a triangle, then the interior angles of a square / 2 = the interior angles of a triangle.

360 / 2 = 180.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to
