Obtuse and isosceles
Isosceles means that at least two of the sides are congruent or equal.
Obtuse means that one angle of the triangle is greater than 90 degrees.
So, your answer is D and E
:)))
Answer:
the slope of the line that passes throught (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(-4,3) and (-8,6)
slop=(6-3)/(-8-(-4))=(3)/(-8+4)=3/-4=-3/4
slope is -3/4

Answer:
SYNTAX PROPERTY
Step-by-step explanation:
If the diameter is at (9,4) and (-3,-2), then the center of the circle is the midpoint of that segment.
and since we know that the radius of a circle is half of the diameter, whatever long that diameter segment is, the radius is half that.
