What are angles that are formed when two lines intersect?
When two unique lines intersect, two pairs of equal angles will be formed. All four angles could be 90 degrees (right angles) if the lines are perpendicular. If the lines are oblique, the pairs of angles can vary (almost) infinitely within a given range (1 degree-179 degrees).The intersection of two lines results in two pairs of equal angles such that the sum of angles equals 360. Another way to state this is that two adjacent angles will always sum to 180 degrees. That said, the best we can do is to express one angle in terms of the other. Call a pair of adjacent angles a and b. In the case of two adjacent angles, a = 180 - b, or b = 180 - a.
What is the adjacent angle to an acute triangle whose hypotenuse is 135 degrees?
The answer should be 67. 5 degrees. The adjacent angle equals the hypotenuse divided by two. After calculation the answer should be approximately 68 degrees.
What shape equals 360 degrees?
The exterior angles of polygons equal 360 degrees.
When two angles added together equal ninety degrees they are said to be?
Two angles are called complementary angles if the sum of their degree measurements equals 90 degrees. One of the complementary angles is said to be the complement of the other.
Find the sum of the measures of the interior angles of a 21-gon?
it equals to 3420 degrees
When 2 straight lines intersect the sum of the adjacent angles equals?
180 degrees
Why does the sum of adjacent angles equals to 180 degrees?
Because that is what a straight line (or straight angle) is.
ABCD is a quadrilateral.does a plus b plus c plus d equals 180 degrees?
No, it equals 360. All interior angles for any quadrilateral are always 360. Usually adjacent angles add up to 180 degrees.
Abcd is a parallelogram ab equals bc and angle abc equals 90 degree explain why abcd is a square?
Opposite sides of a parallelogram are equal. So ab = dc and ad = bc. But you are also told that ab = bc. So all four sides are equal. Opposite angles of a parallelogram are equal. So abc =90 degrees implies that cda is 90 degrees. The remaining two angles add up to 360 - (abc + cda) = 180 degrees and both are equal. So they, too , must be 90 degrees each. So all four angles are equal. A parallelogram with four equal sides and four equal angles is called a square.
Are all complementary angles adjacent?
No, because a complamentary angle just equals 90 degrees. An adjacent angle has a vertex and a common ray the same. If you have two angles that are not touching they cannot be adjacent because they dont have a same ray, but they may have a same vertex. If the two angles add up to 90 degrees they are complimentary and dont have to have anything the same. Hope this helps! If it is confusing look up what an adjacent angle is, then look up what a complamentary angle is! :)
What is A parallelogram with 4 equals sides but no right angles?
Trapezium
What are two angles called whose sum is 180 degrees?
Two angles whose sum is 180 degrees are called supplementary angles. When two angles are supplementary, it means that the sum of their measures equals 180 degrees. This relationship is often used in geometry to solve for unknown angles or to identify complementary angles.
Two adjacent angles with a sum of 90?
Yes, it is possible. For example, line DF equals 90 degrees. Line E bisects Line DF. DE is next to EF, so therefore, they are adjacent.
What is name of a quadrilateral that has 4 sides that are equals but does not have any right angles?
A parallelogram.
Quadrilateral ABCD is a parallelogram in which angle A equals 40 degrees Which two angles below are complementary?
A and B, B and C, C and D, D and A, are all supplementary pairs. The figure has no complementary pairs of angles.
Quadrilateral abcd is a parallelogram in which angle a equals 40 degrees b plus d equals degrees?
280
