• ### Transcript

• 1. Angles In Life Presentation By Audrey Imbs Angles in My Backyard
• 2. Vertical Angle
• Vertical Angles:
• Def: Are an 2 angles formed by lines that intersect. Vertical angles must share common point and be congruent. However, they aren’t adjacent.
• Reasoning:
• 2 angles in
• Lines the intersect to form vertical angles in
• A shared common point
• Are congruent
• 3. Bisected Angle
• Bisected Angle:
• Def.: A ray that divides an angle into two angles that are congruent.
• Reasoning:
• The angles in are divided by the ray in
• Both angles are congruent because they are both about 45 degrees.
• 4. Supplementary Angles
• Supplementary Angles;
• Def.: Two angle measurements, with the sum of 180 degrees.
• Reasoning:
• Two Angles
• The angle measurement for the middle bar is 180 degrees
• 5. Obtuse Angle
• Obtuse angle:
• Def.: A angle that has a measurement greater than 90 degrees, but less than 180.
• Reasoning:
• The angle in has a measurement greater than 90 degrees
• The measurement is about 125 degrees
• 6. Complementary Angles
• Complementary Angles:
• Def.: Two angle measurements, with the sum of 90 degrees
• Reasoning:
• The angles in
• is 50 degrees and the angle in is 40 degrees
• The angles in is 90 degrees
• 7. Right Angle
• A right angle:
• Def.: A right angle is an angle that’s measurement is always 90 degrees.
• Reasoning:
• When measured, the angle in is exactly 90 degrees
• The angle is neither acute of obtuse.
• 8. Acute Angle
• Acute Angles:
• Def.: An angle that has a measure less than 90 degrees.
• Reasoning:
• The angle in has a measure of 45 degrees
• The angle is neither right nor obtuse
• 9. Straight Angle
• Straight Angle:
• Def.: An angle that is completely straight; therefore, it measures to 180 degrees.
• Reasoning:
• The angle in is completely straight and it s measure is 180 degrees.
• 10. Linear Pair
• A Linear Pair:
• Def.: A pair of adjacent angles whose non-shared sides are opposite rays. All vertical angles must be congruent.
• Reasoning:
