7)(3,8)
8)90 °
9)AZ is not a median
Explanation
Step 1
An altitude of a triangle is the perpendicular segment from a vertex of a triangle to the opposite side,so
in the graph, we would have
hence, th coordinate A is
[tex]A=(3,8)[/tex]
Step 2
what is angle ZAX
due to the lines AZ and XY are perpendicular, the intersetion of the lines form an 90 ° angle
Step 3
b)Is AZ also a median? Justify your answer.
median is the line segment from a vertex to the midpoint of the opposite side. It is also an angle bisector when the vertex is an angle in an equilateral triangle or the non-congruent angle of an isoceles triangle.
therefore, the altitude is also the median ONLY for ISOSCELES TRIANGLES,
hence
AZ is not a median
I hope this helps you
