Lines that meet to form 90 degree angles
NettetA vertical and a horizontal line makes the most common right angles. However, diagonal lines intersecting each other also form right angles. If you draw the diagonals of a square, a rhombus or a kite, the angle at the intersection is 90 degrees and is, therefore, a right angle. How to Draw a Right Angle Using A Protractor? Nettet1. We can recognize by what changes occur in the equation of the line.The product of slopes is -1. If the lines are in slope intercept form. $$ y= m x + a \,\rightarrow y= -x/m + const $$. If in full intercept form. $$ \frac {x} {a}+ \frac {y} {b} =1 \rightarrow \frac {x} {b} - \frac {y} {a} = const $$. If in polar form.

Nettet28. jan. 2024 · Solution: The two lines are perpendicular because they intersect at a 90-degree angle. Since one angle is 90 degrees, all of the angles created by the …
Nettet15. sep. 2008 · A right angle is an angle measuring 90 degrees. Two lines or line segments that meet at a right angle are said to be perpendicular. Note that any two right angles are supplementary angles (a right angle is its own angle supplement). Example: The following angles are both right angles. Nettetangles that are opposite from one another at the intersection of two lines; vertical angles are congruent Complementary angles have a sum of 90°. True If angle 1 measures 98° and angle 2 measures 72°, then the two angles are supplementary. False All pairs of vertical angles are equal. True Adjacent angles are always supplementary. False
