200
When triangle NED is congruent to triangle RWO, this is the angle that corresponds to angle WRO.
What is angle END?

What is a square?
200
When triangle NED is congruent to triangle RWO, this is the angle that corresponds to angle WRO
What is angle END?
300
The converse of the conditional: "If you don't water your flowers, then they will wilt."
What is "If your flowers are wilted, then you didn't water them."
300
Will the lengths of 7.3 cm, 5.02 cm and 2.1 form a triangle?
No, they will NOT form a triangle because the sum of the 2 shortest sides is less than the third side.

The reason why you know that a triangle with side lengths of 12”, 16” and 20” is definitely a right triangle.

What is because 12 squared + 16 squared = 20 squared? or What is the Pythagorean theorem?
