Name all the sets of numbers to which each real number belongs. #1. -36/4 #2. 8.2 #3. 0.55555… #4. -√81 Supply check is TOMORROW R drive > Key > Week 11 > Thursday > 10.3 PowerPoint File > Save As > Math > Week 11 > 10.3 PowerPoint Line Segment – Part of a line containing two endpoints and all of the points between them Triangle – Formed by three line segments that intersect only at their endpoints Vertex- The point where the segments of a triangle intersect. Acute Angle – An angle that is less than 90° Obtuse Angle – An angle that is between 90° and180 ° Right Angle – An angle that is equal to 90° Straight Angle – An angle that is equal to 180 ° Angles can be classified by their degree measure Humans have jaws that can open to about 45°. What type of angle is formed by the jaws of a human? Scalene Triangle – A triangle with no congruent sides Isosceles Triangle – A triangle with at least 2 congruent sides Equilateral Triangle – A triangle with all sides congruent Congruent Sides - Sides that have the same length Triangles can be classified by their angles. Triangles can also be classified by their sides
