False. Some quadrilaterals with congruent diagonals are squares, rhombuses, and kites.
t/f is it possible for the exterior angles of a regular polygon to each measure 8 degrees.
False. The sum of exterior angles of any polygon, regardless of whether it is regular or not, is always 360 degrees. If a regular polygon has n sides, then each exterior angle measures 360/n degrees. Therefore, it is not possible for the exterior angles of a regular polygon to each measure 8 degrees, because 360/n cannot equal 8 for any integer value of n.
for the 1st statement This statement is true. Rectangles all have congruent diagonals. All parallelograms require opposite sides to be congruent.
This statement is partially true. Rectangles do have congruent diagonals, but not all parallelograms require opposite sides to be congruent. A parallelogram with congruent opposite sides is called a rhombus.
So would it be true or false?
The statement is partly true and partly false, so it cannot be classified as entirely true or entirely false.
