Basic Coordinates and Geometry

Find the diameter of the largest circular pond that could fit in a triangular garden with vertices at (18,54), (-27,36), and (27,-18), where a unit reprsents 1m.

The Shutter Problem

A rectangle window is framed by two rectangular shutters. The window is twice as tall as it is wide. The shutters are as tall as the window, and their widths are 24 cm. less than their heights. The combined areas of the shutters total the same as the area of the window. Find the heights. The combined areas of the shutters total the same as the area of the window. Find the heights of the window.

Geometric Proof

OK I have no Idea how to do this proof.. I took a test on this section and did horribly.... The problem is this 1.Given: B is the midpoint of AC Bd is perp. to AC Prove Triangle ADC is isosceles (hint: first prove triangle CBD is congruent to triangle ABD The second part uses to same diagram Given DB is perp to AC AD is congruent to DC m of angle C is 70 degrees Find measure of ADB
