Question
a. Given points $R(1,0), S(7,4),$ and $T(11,-2),$ show that $\triangle R S T$ is isosceles.b. The altitude from the vertex meets the base at $K$ . Find the coordinates of $K .$
Step 1
To do this, we need to show that two sides of the triangle are equal in length. We can use the distance formula to calculate the lengths of the sides. The distance formula is given by $\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$. Show more…
