Alternate Angles Corresponding Angles Co interior Angles Nerdstudy

so what are alternate angles corresponding angles and co- interior angles well today we will take you through quick explanation of what each of these angles are imagine that we have two parallel lines now imagine slanted line process through these parallel lines alternate angles are these ones as you can see this one is on this intersections lower left and this one is on its intersections upper right alternate angles will always be equal to each other of course we've also learned from our opposite angles video that opposite angles are equal and this automatically means that all of these are actually equal to each other and obviously these two alternate angles are also equal to each other again of course from opposite angles we know that this means that these are also equal to each other good now let's get rid of all the other angles and just leave these two so we can now focus on the idea of corresponding angles since these two lines are parallel you'll be able to guarantee that these two angles are equal these are called corresponding angles since these angles occupy the same relative position at each intersection where the straight line crosses the parallel lines notice how in this intersection this angle is on the bottom right and how in this intersection this angle is also on the bottom right lastly we've got co- interior angles co- interior angles are angles on the inside of each intersection where the straight line crosses notice how this one is on the bottom right of its intersection and this one is on its top right also if we're working with two parallel lines and slant like this example then the co- interior angles are always supplementary angles and that they will add up to become 180° so all in all other than memorizing the names of the angles you can just remember this one figure and it will help you to find the angles that you are looking for well that's it for this video and until next time have good one
