Make it Right!
The vertices of a right triangle are at A = (2, 2), B = (5, 4) and C = (3, k). Find all possible values of k.
SolutionIn order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.
NOTE: The given solution provides two significantly different methods for solving this problem. One method relies on the point-to-line distance formula; the other uses trigonometry.
Find the perimeter of a triangle formed by the lines whose equations are:y = 3
x = 2
y = -
- Line A has a slope of 3
- Line B forms a 30º angle with line A
Find all possible values of the slope of line B.
