Are all 45 45 90 triangles are similar to each other?
Yes or they could be congruent to each other.
If two triangles have three pairs of congruent angles are the triangles guaranteed to be congruent?
No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.
What shape is made out of triangles?
A pyramid could be constructed from 4 or more triangles.
Is an octagon made out of triangles?
Yes, an octagon could be considered to be made out of 8 triangles.
What is the least amount of triangles you could fit into a nonagon?
The smallest number of triangles that you could divide a nonagon into is seven.
Are acute triangles similar?
Not necessarily. Just because two triangles are both acute doesn't make them similar. They could be similar, but not necessarily.
If two triangles have three pairs of congruent angles then the triangles are guaranteed to be congruent is that true or false?
trueImproved Answer:-It is false because the triangles could be similar in shape but not in size
If two triangles have three pairs of congruent angles then the triangles are guaranteed to be congruent true or false?
False, because they could be similar triangles having the same angles but proportionally different side lengths
How many triangles are there within a nonagon?
if you need to know how many triangles are in a polygon ... just take the number of its sides and subtract for example. nonagon has 9 sides so it will be 9-2=7 so, a nonagon has 7 triangles
Could triangle ACB be similar to triangle DCE?
If triangles ABC and DCE have the same angles then yes otherwise no.
Are all 45 45 90 triangles are similar to each other?
Yes or they could be congruent to each other.
Why can't you use AAA to prove two triangles congruent?
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably be used to prove two triangles are similar not congruent.

What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment with the endpoints of -12 0 and 12 0?
To get the midpoint between two points, the x-coordinate of the resulting point is the average of the x-coordinates of your two points. Similar for the y-coordinate. Take the average of the endpoints, calculate the average of the x-coordinates.

Yes, an octagon could be considered to be made out of 8 triangles.
When do you say that two triangles have the same shape?
well, they could be congruent, there are some rules for congruency, to be congruent two triangles have, ASA-two angles the same with a side length between them. SAS-two side lengths the same and a same angle between them. SSS-all 3 side lengths the same. RHS-if the triangles are right angles ,and the hypotenuse are the same. ;or they could be mathmatically similar. :)
