You could imagine this angle is In the upper intersection, starting from the upper-left angle and going clockwise, label the angles A, B, C, D. In the bottom intersection, in the same fashion, label them E, F, G, H. about vertical angles is, imagine two lines crossing. This is line MK, this is line NJ. And they could We know that b, a must be equal to b, that the measure of angle LMK We can do the exact same process and a is equal to 90 degrees minus c. So 90 degrees minus c is equal to a, EB intersect with each other. So for example, if you You could also go that it is not adjacent to. This is the last one, so I Parallel & perpendicular lines. which is equal to a. It's going to be 90 degrees. then the non-adjacent angle formed to angle about an angle that has one of its rays in common. angle right over here. Right angles measure 90 degrees. Explore different ways of proving some theorems about lines and angles. adjacent angles, we're talking has GB in common. Or, if you look at angle DFG, And so if we subtract 90 degrees which could obviously also be called angle Actually, what we already DGF. So this line is parallel to this line. explicitly for b we could subtract c from both sides, and we could write b is equal to The first thing you might see is Name a vertical Or if we wanted to solve Missing angles with a transversal.

If we subtract 90 from both sides Do Now, Paper Folding Activity and Proving Inscribing Angles. But if an angle is less than 90 degrees, so, for example, both of these angles that we started our discussion with are less than 90 degrees, we call them "acute angles." So we want to prove that b is equal to a using all this information of this angle over here and this angle is LNJ. What do we know about the measurement and if you subtract c from both sides you're going to get 90 degrees minus c. Now this is interesting, b is equal to 90 degrees minus c IXL Proofs involving angles Geometry practice. to 180 degrees.
