What I Need to Know – Right Triangles How to Prove a Quadrilateral is a Specific Figure Parallelogram Rectangle Rhombus Opp. Sides are Parallel Opp. Sides are Congruent; 4 right angles All 4 sides are Congruent Square All 4 sides Congruent & 4 Right Angles Isoc. Trapezoid 1 pair parallel sides; other sides congruent 1 pair parallel sides Opposite angles are supplementary

What I Need to Know – Right Triangles All sides are congruent All angles are congruent 3 4 5 Sum of interior = (n-2)180 Sum of exterior = 360 6 7 8 Interior = 180 – ext. 9 10 12 Given interior: 180 – int. = ext. Given Exterior: 180 – ext. = int. 360/exterior = n

What I Need to Know – Right Triangles Equilateral Triangle Square A repeated pattern with no gaps or overlaps that covers a plane Part of Circle Area Regular Hexagon Only REGULAR polygons that have an interior angle measure that is a factor of 360 will tessellate. Part of Circumference

What I Need to Know – Right Triangles P*P=P*P ab = cd OW=OW aa = b(b+c) Conehead ac = ab

What I Need to Know – Right Triangles Congruent chords intersect congruent arcs The angle between the tangent line and the radius is 900. The radius is the distance from the center to a point on the circle. (h, k) -- POOP r 2 r

What I Need to Know – Right Triangles Distance Formula: find the diameter length Distance formula to find radius Use the center (h, k) and radius to find Radius is half the diameter equation. Midpoint formula to find center of circle Plug h, k, and r into equation. Plot center of circle on graph paper. From the center, count up, down, left and right the length of the radius. Mark points and draw circle. USE DESMOS!! Very easy. Just enter equation.

What I Need to Know – Right Triangles Units cubed. Space occupied B means area of the base b means length of the base BIG DIFFERENCE!!! Units squared. Material to cover.
