2. obtuse angle right angle 3 types of angles an angle that measure exactly 90 degrees. an angle that measure greater than 90 degrees acute angle an angle that measure less than 90 degress

3. Scalene Triangle: A triangle who will always have no sides equal in length. Isosceles Triangle: A triangle who has two equal sides Equilateral Triangle: A triangle who has all equal sides. 3 Type of triangle

4. Acute triangle: a triangle that measure less than 90 degrees. Obtuse triangle: a triangle that measure more than 90 degrees. Right triangle: an angle that measure exactly 90 degress. 3 types of triangles named by angles.

5. Intersecting Lines: Two or more lines that meet at a common point. Perpendicular Line: Two lines that meet to make a 90 degree angle. Parallel Lines: A line that will never intersect. LINES

6. Congruent mean an equal line. for example, a rhombus have all congruent sides. Congruent

7. Adjacent Angles Two angles that share a common side but do not overlap each other.

8. Vertical angle is made when two lines intersect, the angle are not adjacent. Vertical angle are always equal in measure. Vertical Angle

9. Supplementary Angles Two angles for which the sum of their measure is 180 degrees

10. Complementary Angle Complementary angle is when two angle have a sun of 90 degrees

11. Types of Quadrilaterals Square: four congruent sides, four right angles that are congruent Rhombus: four congruent sides opposite angles are congruent Trapezoid: one set of parallel sides, Parallelogram: two pairs opposite sides parallel, opposite angles are congruent Rectangle:two pairs of congruent sides and four congruent angles

12. Part of circle Radius, is a distance from the middle of circle to the endpoint Diameter, is a distance from the end point of the circle to the other end point

13. Perimeter and circumference Perimeter: Perimeter is a path that surround an area side+ side + side + side Circumference: The circumference of a circle is the length around it. C= Pi times diameter 3+3+7+7=20
