Given ABCD is a rectangle
Prove ABD has congruent diagonals

Identify the steps that complete you the proof.

6. opposite sides of a parallelogram are congruent

Don't we already know the opposite sides of a rectangle are congruent without six steps?

8. SAS  Side Angle Side Theorem

They picked the wrong triangles, they should show

BAD is congruent to ABC

9. They're probably looking for CPCTC, corresponding parts of congruent triangles are congruent.  But AC isn't in either of the triangles they showed congruent.

My professional opinion is this question sucks.

Club Symbol = parallelogram side theorem

Diamond Symbol = SAS

Spade Symbol = CPCTC

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
