What is the complement of 15 degree angle?
Complementary angles total 90°. The complement (or complementary angle) of 15° is 75° (90 - 15).
What quadrilateral has two pairs of equal lines one pair of equal angles and one reflex angle?
This is an arrowhead quadrilateral.
If three angles of a quadrilateral measure 90 87 and 90 what is the measure of the fourth angle?
Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.Calculate the fourth angle so that the sum of the angles is 360 degrees.
What are opposite angles?
Opposite angles are angles across from each other in intersecting lines. For example, see the figure below:a-> X
Two angles are complementary the measure of the larger angle is twice the measure of the smaller angle find the measure of the larger angle?
the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
Can an angle have two pairs of vertical angles and two pairs of congruent angles?
No. An angle can have only one angle!
Which pairs of angles are vertical angles?
Actually, It is this. Question: Angle 1 and 4 are called ___ angles? Answer: Supplementary
Which of the following angle pairs are alternate interior angles?
angle 3 and 5
What are pairs of angles?
1.) Acute Angle 2.) Obtuse Angle 3.) Right Angle
What is a angle are pairs of opposite and congruent angles formed by intersecting lines?
Vertical angles
Which angle pairs add up to 180?
Supplementary angles
What angle are pairs of opposite and congruent angles formed by intersecting lines?
Corgent Angles
What angle is two pairs of opposite and congruent angles formed by intersecting lines?
Such angles are called vertically opposite angles.
Why do all linear angle pairs must be supplementary but all supplementary angles do not have to be linear pairs?
All supplementary angles would be linear pairs IF they were adjacent. But they could be far apart.
What does angle angle side mean?
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
What Quadrilateral has 2 pairs of equal angles?
A parallelogram has two pairs of equal angles, but each pair may be at a different angle. A rectangle has two pairs of equal angles that are also equal to each other.
If two triangles have three pairs of congruent angles the the triangle is congruent?
Yes they are. Or they could have three pairs of congruent sides, or they could have one pair of congruent angles and two pairs of sides. As far as a triangle goes, if you have at least three pairs of congruent sides or angles they are congruent. This answer is wrong. The triangles are only similar. For congruent trisngles we have the following theorems = Side - side - side, Side - Angle - side , Angle - angle - side, Right triangle - hypotenuse - side.
