4.02 Congruent Triangles, doess anyone have tips on how to do this? im getting confused with the SSS, SSA , SAS
Bogdan [553]
SSS is side side side so all the sides have to be congruent for the triangles to be congruent.

SSA is side side angle so two sides and an angle needs to be congruent for the triangles to be congruent.

SAS is side angle side so two sides and an included triangle need to be congruent for the triangles to be congruent.

Hope that helps:)

John ran 4 laps of the track in 5 minutes, 40 seconds
mihalych1998 [28]

Well, lets think about this. We need to ask our self how many seconds are in one minute. There are 60 seconds in 1 minute. We know he did 4 laps in 5 minutes and 40 seconds. You can change the minutes to seconds by multiplying 60 * 5 = 300 seconds. So 5 minutes = 300 seconds. Now just take the 40 seconds and add it to the 300 seconds, which will give you 340 seconds. So John ran 4 laps in 340 seconds. B wants to know how many seconds it took John per lap...We can find this by dividing 340 by 4 340/4 = 85.

A) 340 seconds

B) 85 sec/lap
