How did you verify that triangle ABC is isosceles?
7b) Look at the lengths of all 3 sides of triangle JKL. What type of triangle is triangle JKL?
7c) What is the perimeter of the triangle JKL?
7d) What is the area of triangle JKL?
pg 125 10c[br]State the area of Triangle ABC.[br]State the area of Triangle DEF.[br]Verify that the area of Triangle ABC is four times the area of Triangle DEF.
5b) On the graph above, find the midpoint of each side. Join the midpoints of adjacent sides to form a new quadrilateral TUVW.
5c) Verify that opposite sides of TUVW are parallel (use the slope tool to find the slope of each of the 4 sides of TUVW).
5d) Verify that opposite sides of TUVW are equal in length.
5e) Drag a point from PQRS and see if the properties you found in 5c and 5d remain true. What do you notice?
