Two lines are perpendicular if and only if they form right angles. express the given biconditional as the conjunction of two conditionals. a. if two lines are perpendicular, then they form right angles. if they form right angles, then the angle measures 90. b. if two lines are perpendicular, then they form right angles. if they form right angles, then they are perpendicular. c. if the angle formed by two lines measures 90, then the lines form right angles. if they form right angles, then the angle measures 90. d. if two lines are perpendicular, then the angle measures 90 if they form right angles, then the angle measures 90.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
