Explain why all isosceles right triangles are similar, but not all scalene right triangles are simliar.

All isosceles triangle  are similar because the three angles are the same for example when 2x= 90, x =45 degrees.

For all scalene right triangles are not similar  When x =45, then 90-x = 45

Step-by-step explanation:

All right isosceles triangle  are similar because the three angles are the same  

If one angle is 90, The other two that are equal must make up to 90 degrees  for example 2x = 90 , x =45 degrees  

Therefore, the three angles in an isosceles right triangle are always 90,45,45.

For the  scalene right triangle,  we  can have 90, 80, 10 angles triangle or a 90, 50, 40 triangle or 90, 30, 60 triangle.

Generally, we can also have this: 90, x, and 90-x angles so depending on x , the angles of different. 

Right scalene triangles will be not be similar, When x =45, then 90-x = 45

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
