Answer: A
a quadrilateral with all four angles right
Step-by-step explanation:
A quadrilateral is a rectangle if a quadrilateral has all four angles right,
a parallelogram with congruent sides
a quadrilateral with diagonals that are congruent and bisect each other
a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which
are parallel and congruent. And all its angles are congruent.
But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.
Answer:
b
Step-by-step explanation:
Answer:
The smaller angle is 45 degrees.
Step-by-step explanation:
Angles measure 180º. If there are two angles and one of them is three times the other, you would just divide 180 by 4.
The equation would look like:
3x + x = 180
First, the x would be added together:
4x = 180
Then, divide both sides by 4:
x = 45
