Answer:
an acute triangle
Explanation:
All of the angles are less than 90 degrees, which is an acute triangle.
The answer to the equation is 18 which is a composite whole number. the answer is C
The sides of an isosceles right triangle are in ratio 
.
Answer: 14√2
Answer:
Step-by-step explanation:
1 and 2 are linear pairs
1 and 3 are verticle
4 and 5 are adjacent
well, a and d are true, and b is somewhat false...
angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90
c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one
so b and c may be true, im not sure
i know that a and d are true, therefore they are not the right answer
