I doubt it. If I put the base of a right angle triangle on one of the parallels and the opposite apex on the other parallel line, there is a side at right angles to both lines, but the hypotenuse might be sloping down at any angle you like.
If you are given the distance between the parallels, then you must be given the length of the base or the smaller base angle to fix a particular right-angled triangle.
Similar in the number of sides but not congruent
Not as a rule, though they can be.
No.Examples:The right angled triangles {3, 4, 5} & {6, 8, 10} are similar;The right angled triangles {3, 4, 5} & {5, 12, 13} are just two right angled triangles.
The seven types of triangles are Isosceles, equilateral, scalene, equiangular, acute-angled, obtuse-angled, and right-angled
Right angled triangles!
Yes, you are allowed to draw two acute angled triangles. Acute means less than 45 degrees. - lovelytoes
Right angled triangles do!
Right angled triangles.
The checking for right-angled triangles is RHS:Right angle - they both haver a right angleHypotenuse - the hypotenuse of the triangles are congruentSide - a corresponding side of the triangles are congruent.
There are 18, but only 7 primitive ones. The rest are similar to the primitive triangles : for example (15, 50, 25) is similar to (3, 4, 5).
