An isosceles triangle has vertices at (1,1) and (3,3) what are the coordinates of the third vertex

Find the area of the triangle shown 3 by 6

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9
