Step-by-step explanation:

Quadrilaterals whose diagonals intersect at 90 degrees/or form right angle  are - a square, a rhombus, and a kite.

Also the diagonals of these quadrilateral divide each other into equal halves at the point of intersection

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
