Answer:
The length of the three sides 
The triangle <u>is not</u> a right triangle
Step-by-step explanation:
A = (3, 2) , B = ( 6, 9) , C = (10, 6)
Find the lengths using distance formula.




Using Pythagoras theorem :

Longest side is AC . So we will check if it satisfies Pythagoras theorem :

65 ≠ 58 + 25
So the sides does not satisfy Pythagoras theorem. Hence the triangle is not a right triangle.
The answer is -6
Step-by-step explanation:
Because when you time 3 bye a negative 2 you get a negative 6
3 units down would be subtracting 3 from the Y values and 4 units left would be subtracting 4 from the X values
Point A is at (2,-1)
The new point would be at (2-4, -1 -3) = (-2,-4)
Point B is at (1,-4)
The new point would be at (1-4, -4 -3) = (-3,-7)
Point C is at (3,-5)
The new point would be at (3-4, -5-3) = (-1,-8)
Point D is at (5,-3)
The new point would be (5-4, -3-3) = (1,-6)
So the new location would be:
A' (-2,-4)
B' (-3,-7)
C' (-1,-8)
D' (1,-6)
Answer:
This is an isosceles right triangle so 45 45 90 degrees because both the opposite and the adjacent are the exact same measure
Thus, Angle E is equal to 45
