In the figure below, points B, D, and C are co-linear, and AD is perpendicular to BC. Line segment AB is 10 units long, and BC is 30 units long. Also, AB is perpendicular to AC. How many units long...

Two angles of a triangle have the same measure and the third one is 39 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.

There is a right triangle, ΔABC, where ∠C is the right angle, making AB the hypotenuse. There is altitude CD drawn to the hypotenuse, thus forming ΔACD and ΔCBD, similar to each other and the original...

Segment JK has coordinates J(3,-6) and K (-3,2). When segment JK is dilated with a scale factor -4, what are the coordinates of J' and K'? A. J'(-1,-10) and K'(-7,-2) B. J'(7,-2) and K'(1,6) C...

In ΔABC, the points M and N lie 5/8 of the way down the sides on which they lie.    Prove:  i.  Line Segment MN is parallel to the base Line Segment BC ii...

Consider the triangle with the vertices: A=(1,2) B=(-1,8) C=(7,10) a. find the midpoint M of Line Segment AB b. find the midpoint N of Line Segment AC c. Verify that Line Segment MN is...

theres a square, namely ABCD (clockwise from top right corner). AB=18 & AD=12. K&L are on AB so that AK=1/6 AB & BL=1/3AB.... M&N are on CD so that CM=MN=1/4CD... KM...
