1 a)Name each of these three shapes. b)The endpoint A of AB is at (1,3). The midpoint is at (4,8). Where is B? Graph them. c)Find the three quarterpoints along AB where A = (2,4) and B = (10, -4). d)What is m <1 ? e)What is the midpoint between (3,-10) and (-5, -10)? f)Name the angle <2 in every way you can: g)Define collinear? 1 35° 1.5 Triangles and Special Quadrilaterals B P M 2

2 h)Is this polygon convex or concave? How do you know? j)Give three names for the polygon. k)Draw an equiangular polygon. l)Write a congruency statement for the triangles below. m)Draw an example of a linear pair. n)Draw an example of vertical angles. A G L D F C O A N L 1.5 Triangles and Special Qudrilaterals 1.5 Triangles and Special Quadrilaterals R

3 2.A Quick Word on Assumption a)When you assume: You make an ass out of you and me. b c d a none How about now? ab bc a || c c)Which lines are perpendicular a b c d b)Which lines are parallel?

4 2.A Quick Word on Assumption Things you may not assume: You may not assume that just because two lines or segments look parallel that they are parallelthey must be marked parallel! You may not assume that two lines are perpendicular just because they look perpendicularthey must be marked perpendicular! Pairs of angles, segments, or polygons are not necessarily congruent unless they are marked with information that tells you they must be congruent!

5 3.How To Score Easy Points On Tests a)Make an ass out of Mrs. Paunovska. Sample Test Question a b c f e d Write the congruency statement: Yes! They look congruent but nothing has been marked congruent!...So the triangles are NOT CONGRUENT

6 4.Notes Right triangleObtuse triangleAcute triangle Scalene triangleIsosceles triangleEquilateral triangle

7 4.Notes Trapezoid

8 4.Notes TrapezoidParallelogramKite RhombusRectangleSquare += Parallelogram is a trapezoid with 2 additional parallel sides A rhombus is a kite with same sides.

9 4.Notes TrapezoidParallelogramKite RhombusRectangleSquare The point being that it doesnt matter what it LOOKS like. Only what its marked up as.
