Which pair of angles must be congruent?
An angle is the intersection of two rays with a common endpoint. Adjacent Angles are 2 angles that share a common vertex, a common side and no common interior points.
How many angles are formed by 5 noncollinear rays intersecting at a common end point?
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
The midpoint of CD is m -1 -2 one endpoint is C -9 -4 what is the other endpoint?
The other endpoint is -5,-8.
The midpoint of JK is point L at ( and ndash1 8). One endpoint is J(4 and ndash15). Which equations can be solved to determine the coordinates of the other endpoint K Check all that apply?
If endpoint J is at (4, 15) and midpoint L is at (1, 8) then endpoint K is at (-2, 1) Because (4-2)/2 = x and (15+1)/2 = y for midpoint (1, 8)
What is the endpoint formula?
The endpoint formula isY2 = (Ym * 2) - Y1X2 = (Xm * 2) - X1as in Ym is the y midpointand in Xm is X midpointyou can also right the endpoint formula as{ (2Xm) - X1 , (2Ym) - Y1 }(X,Y)for example:You have endpoint (2,5) midpoint (3,6)what is the endpoint of this3 * 2 = 66 - 2 = 46 * 2 = 1212 - 5 = 7answer is (4,7)Now lets prove thatuse the midpoint formula,Ym=(Y2+Y1)/2Xm=(X2+X1)/24 + 2 = 66 / 2 = 37 + 5 = 1212 / 2 = 6The midpoint should be (3,5) and it is.
