What is the definition of a square?
a plane figure with four equal straight sides and four right angles
Good. Let's go through each part.
i think it f and d
It has 4 right angles. Part A. Does that make it so that consecutive sides are perpendicular?
Correct, so part A . is true.
Part B. Angles W and X are both right angles. Are they congruent?
Correct. Part B. True.
Part C. What are supplementary angles?
e is wrong
You're on part E already?
x an y i think
I don't understand your answer. Let's look at part C. The question deals with supplementary angles. What are supplementary angles?
angle add up to 180
Definition of Supplementary Angles: Two angles are supplementary if their measures have a sum of 180 degrees.
so c is right
Correct. Since all 4 angles of a square are right angles, each angle has a measure of 90 degrees. That means any two angles of a square are supplementary angles because 90 + 90 = 180.
Now we do D. Do you know what a rhombus is?
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
Correct. A rhombus is a parallelogram with all 4 sides congruent. Is a square a parallelogram with all 4 sides congruent?
so d is right
Corect. D. True E. You already wrote above False, and you are correct. A trapezoid has to have exactly two sides parallel, which means the other two sides cannot be parallel. A parallelogram can never be a trapezoid.
D. True E. False
thank for your help
and f is true
Part F. A square is a parallelogram. A parallelogram is a quadrilateral with two pairs of parallel opposite sides.
Correct. F. True
Great job. I see you know your stuff!
