Which of the following would you find most useful in giving a coordinate proof that two triangles are congruent by sss? a: distance formula b: midpoint formula c: cpctc d: slope formula

Polygon mnopq is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image m′n′o′p′q′. the coordinates of point m are (2, 4), and the coordinates of point n are (3, 5). the slope of is .

On a cm grid, point p has coordinates (3,-1) and point q has coordinates (-5,6) calculate the shortest distance between p and q give your answer to 1 decimal place

What is the area of the shaded sector?
