Can somebody help me with this Similarity Theorems?

There are three triangle similarity theorems that specify under which conditions triangles are similar: If two of the angles are the same, the third angle is the same and the triangles are similar. ... If two sides are in the same proportions and the included angle is the same, the triangles are similar.

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
