Yesterday, we did three worksheets as a review for our quiz today.
The first, (2.4) Special Pair of Angles, which talked about complementary, supplementary and vertical angles. Complementary angles are 90 degrees in measure while supplementary are 180 degrees in measure. Vertical angles are angles right across from each other.
1&3 are vertical angles. 2 &4 are also vertical angles. One thing about vertical angles you have to remember is that they are ALWAYS congruent.
Since b & d are vertical angles, then b equals 40 degrees.
The second worksheet, (2.5) Perpendicular Lines, focused on perpendicular lines mostly. Perpendicular lines are when two lines intersect and create 90 degree angles, or right angles. The definition of perpendicular lines are:
If two lines are perpendicular, then they form right angles.
If two lines form right angles, then the lines are perpendicular.
Important properties to remember are:
If two are perpendicular, then they form congruent adjacent angles.
If two lines form congruent adjacent angles, then the lines are perpendicular.
If the exterior sides of two adjacent acute angles are perpendicular, then the angles complementary.
On our last worksheet, (2.6) Planning a Proof, we reviewed on planning proofs. Which is where you explain what you will do in your proof before you do it.
All of these were on the quiz today. Hopefully you all did amazing.
Oh and go but Mindless Behavior’s album #1 Girl. I’m listening to it now and it’s amazing.
NEXT SCRIBE IS J.D
