What else can I help you with?
Is an acute angle and an obtuse angle sometimes always or never complementary?
Two angles are complementary when they add up to exactly 90 degrees. An obtuse angle is by definition greater than 90 degrees. Therefore, an obtuse angle cannot have a complementary angle. So an obtuse angle and an acute angle are never complementary.
How many acute angles does a trapezoid have?
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
If two sides of two adjacent acute angles are perpendicular then the angles are called what?
Complementary
Can two complementary angles both be acute?
They MUST both be acute.Two angles are complementary if their sum is 90 degrees. Therefore, neither of them can be greater than 90 degrees and so they are acute.
What are two angles whose measures add up to 90 degrees?
They are "complementary" angles, and both are obviously acute angles.
Is two acute angles are always complementary?
No
Can two acute angles cannot be supplementary?
Two acute angles cannot be supplementary but they can be complementary
If two angles are complementary then the angles are acute?
True.

Does a parallelogram have all right angels?
no it has two acute acute and two obtuse
How many acute angles does a trapezoid have?
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
What property of two acute angles of a right triangle have?
They are complementary.
Can two acute angles be complimentary?
In every pair of complementary angles, both of them are acute angles.
If two sides of two adjacent acute angles are perpendicular then the angles are?
Complementary.
What are the angles if the two sides of two adjacent acute angles are perpendicular?
Complementary
Can a triangle have two acute angels?
yes
If a polygon is a right angle then the two acute angles are complementary?
yes
