12. Kaya said that a rectangle can be a rhombus. Explain whether Kaya's statement is correct.
13. Andy said that a quadrilateral can have exactly 3 right angles. Explain whether Andy's
statement is correct.​

Answer 1

Answer:

idk about 12 and 13 but the number of acute angles a triangle can have is 2 and for 11 No, a triangle cannot have an obtuse and a right angle.

12) kayla's statement is incorrect because the diagonals of a rectangle do not intersect each other at 90 degree like a rhombus.

13) Andy’s statement is incorrect because

Quadrilaterals have 4 sides and 4angles. The exterior angles of any convex polygon add up to 360 degrees ( 4 right angles). If an interior angle is a right angle then the corresponding exterior angle must also be a right angle
