A linear pair of angles is formed when two lines intersect. Lines can be vertical.-----B.) For two angles to be adjacent, they only have to share a leg, which puts no restrictions on whether the non-common legs form a straight line or not. Login. But two supplementary angles might or might not form a linear pair, they just have to "supplement" each other, that is their sum should be 180^o. We know acute angles are angles whose measure is less than 90°. A linear pair forms a straight angle which contains 180?, so you have 2 angles whose measures add to 180, which means they are supplementary.

Congruent angles can also be denoted without using specific angle measures by an equal number of arcs placed around the vertices of two angles, as shown below. If two angles form a linear pair, the angles are supplementary. Check which of the following pairs of angles form a linear pair (Fig 5.13): 5.2.5 Vertically Opposite Angles. The measure of an angle is three times the measurement of its complement. The measure of one angle is 24 more than the measure of the other angle. Forming a linear pair means two angles have a sum of 180 degrees. A pair of scissors is a classic example of Linear Pair of angles, where the flanks of scissors, which are adjacent to each other and have common vertex O, form an angle of 180 degrees. equal to 180 and solve for x: Now plug in the value of x to solve for .
