In the triangle shown below, the angles A and B are complementary because they have a sum of 90º. This is obvious since angle C is 90º and the other two angles must have a sum of 90º so that the three angles in the triangle together have a sum of 180º. It is always true that the two acute angles in a right triangle are complementary.
Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity. MCC9-12.G.SRT.5 Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.

As these two lines are parallel, we can use the Alternate (or Z angle) fact to label the two more angles y and z as below. We know that the angle on a straight line on a straight line is 180°, so we can say that x + y + z = 180°. Therefore the interior angles of a triangle add up to 180°. Interior Angles of a Quadrilateral

Steps 5, 6 and 7 are straightforward to understand once you know what the words mean. The intersection line is the line made by the intersection of the two planes. Each triangle lies in a plane. There are three cases: the planes are parallel and do not intersect. The triangles obviously do not intersect. the planes are the same plane.

I can identify angles created when a parallel line is cut by transversal (alternate interior, alternate exterior, corresponding, vertical, adjacent, etc.). I can justify that the sum of the interior angles equals 180. (For example, arrange three copies of the same triangle so that the three angles appear to form a line).
Since ( -1 - (-1) ) = 0 and the division by 0 is not defined, the slope of the line is undefined and the line is vertical. (parallel to the y axis). Solution to Q5: In what follows, m1 is the slope of line L1 and m2 is the slope of line L2. a. Find the slope m1 of line L1 and the slope m2 of line L1 m1 = ( 1 - 2 ) / ( 3 - 1 ) = -1 / 2

Line segments AB and DE are parallel, and line segment HI is a transversal. Therefore, ∠BKM and ∠KML are same-side interior angles. Since same-side interior angles are supplementary, m∡BKM + m∡KML = 180°. m∠BKM + m∠KML = 180° Set up the equation. m∠BKM + 32° = 180° Substitute 32° for the measure of ∡KML.
