The figure below shows adc and bec. complete the two-column proof. be ac and ad cb cb ≅ ca prove: adc ≅ bec statement reason be a0 and ad cb cb ≅ a1 given a2 and bec are right angles perpendicular lines form a3 angles a4 = a5 a6 property adc ≅ a7 a8 postulate

We can fill the columns with help of below explanation.

Explanation: Here, we have a figure in which we have two triangles  ADC and BEC.

And required prove is  

and ( given)

And, (given)

and are right angle triangle.( perpendicular lines form 90° angle)

So,

( Common angle property )

( ASA postulate)

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

n
