Can an isosceles triangle be an right triangle?
Yes it can... the side length has nothing to do with the angle measures... I am in 6th grade and i just took the test on this, i got 100%...
Why is a right triangle cannot be an equilateral triangle?
An equilateral triangle has 3 sides of equal length (that's what the word equilateral means) and also 3 equal angles, all of which are 60o. A right triangle, by definition, has one right angle of 90o. So if all the angles are 60o then it is not possible to have an angle of 90o, right? COOL!!!!!!!!!I GOT AN A+ on my portfolio thanks to this answer
Why is an obtuse triangle called its name?
An obtuse triangle got its name from Egypt. Ob in egyptian is lage tuse is angle
Things that are shaped like a right triangle?
A folded napkin is often folded into a right triangle, but that's all I got. Sorry!
How many equal right angles has an isosceles triangle got?
none - it's an isoscelese triangle it doesn't have right angles. It has two equal angles (both acute) and one other andgle (also acute)
How many perpendicular lines has a triangle got?
two if the triangle has a right angle
What shape has got 1 acute angle?
any right triangle will have an acute angle in it
Has a triangle got square corners?
Only if it is a right angle triangle which will have only 1 square corner of 90 degrees

Which postulate or theorem can be used to prove that triangle ABD is congruent to triangle CDB?
SSS
Could a obtuse triangle have a right angle?
No because a right angle is 90 degrees and an obtuse has to be more that 90 degrees... it is usually 180 degrees (I think) BUT AN OBTUSE ANGLE IS MORE THAT 90 DEGREES.... * * * * * Nearly correct. An obtuse angle is anything between 90 and 180 degrees. If you had a triangle with a right angle AND an obtuse angle, those two angles would sum to more than 180 degrees. But all three angle must sum to 180 degrees so the third angle has a bit of a problem - it has got to be negative!

What ratio of the opposite leg length to the hypotenuse length?
its the cosine.. thanks to the dude up there i got it wrong and that was my answer for 4.1.3.
Calculate a side of a triangle?
Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..

How do you draw one and a half right angle turns?
you just draw one right angle and draw one half of a right angle and connect them together and wella you got one.
