Angles, parallel lines, & transversals. parallel lines are lines in the same plane that go in the same direction and never intersect. when a third line, called a transversal, crosses these parallel lines, it creates angles. some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection). So this angle right over here, 9x plus 88, this is going to be equal to 9 times negative 6 plus 88. 9 times negative 6 is negative 54. let me write this down before i make a mistake. negative 54 plus 88 is going to be let's see, to go from 88 minus 54 will give us 34 degrees. so this is equal to 34, and it's in degrees. Learn. angles in a triangle sum to 180° proof. isosceles & equilateral triangles problems. triangle exterior angle example. worked example: triangle angles (intersecting lines) worked example: triangle angles (diagram) triangle angle challenge problem. triangle angle challenge problem 2. triangle angles review.

The angle addition postulate states that if a point, p, lies inside an angle b then m∠abp m∠pbc=m∠abc. in other words, the measure of the larger angle is the sum of the measures of the two interior angles that make up the larger one. when two lines intersect and form 4 angles at the intersection, the two angles that are opposite each. Remember: adjacent angles on a straight line are supplementary. if they are adjacent angles on a straight line, then they add up to 180°. example: determine, with reason, the value of ;: statement reason ;=180°−120° adj ∠′s on a str line in geometry we always need to provide reasons for ‘why’ we state something. exercise 2:.
