In quadrilateral BADC, AB = AD and DC. The line AC is a line of symmetry for this quadrilateral.
a. Based on the line of symmetry, explain why the diagonals AC and BD are
perpendicular.
b. Based on the line of symmetry, explain why angies ABC and ADC have the
same measure.

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.
