Finding the angle for an isosceles triangle roof
You are trying to assemble a triangle with inclined parts of 8 units in length and horizontal line is 7 units. The rest is math:
∠α = cos⁻¹(3,5÷8) = 64.0555°
Due to slight imperfection in LEGO ...

Is there a 90 degree angle brick?
There are many different types. You can find them here: Bricklink - Brick Modified
There are also Brackets: Bricklink - Brackets
And you could use some of these Bricklink - Plate Modified or, of ...

What techniques can be used for laying plates at 45° angle?
This is in old question but I think many people find this helpful.
I accidentally found this Lego technique where you put a 4x4 round plate between four 1x1 round plates. You can see in the picture ...

Is there a 90 degree angle brick?
The part# 87087 - "Brick, Modified 1 x 1 with Stud on 1 Side" could work:
But the part# 11211 - "Brick, Modified 1 x 2 with Studs on 1 Side" seems better to scale up with:

Is there a 90 degree angle brick?
There are many. I believe the classic "Erling"/headlight brick (it was designed by a guy named Erling) is the oldest way, but there's also a number of bricks with studs on the side and a number of ...

Finding the angle for an isosceles triangle roof
To get the exact answer, this is what high school geometry and trig is useful for in the real world :)
Alternatively, switch off collision detection and just try changing the angles in small ...

Is it possible to create a slope (roof hip) on a 45 degree angle?
A 45 degree slope doesn't fit the standard geometry of the LEGO system.
The basic "3D module" of the system (a 1x1 plate) is 5 units square by 2 units tall.
A brick is three plates tall - i....

How can I build a Lego slope of a rough 50 degree angle with preferably legal building techniques?
You can always invert your "escalator piece" to use as a base as it will make exactly same angle. Then it is up to you how you want your guiding rail to be attached. Here's one idea:
Please ...

How can I build a Lego slope of a rough 50 degree angle with preferably legal building techniques?
The bar elements in your step part are vertically separated 3 plates and horizontally 1 module which is 2.5 plates. So the exact angle (rather than approximately measured) is atan (3/2.5) = 50.1944289 ...

At a small scale the part Wedge 2 x 2 (Slope 45 Corner) could do this, but this approach can't be scaled up:
