# Question Regarding Creating Right Angle in Manim

I was recently making a program in the python manim library that included right angles. I tried searching up how to create right angles in manim, but could not find anything. I was wondering if anyone could help me in creating a right angle in the python manim library.

Thank you in advance.

Use the RightAngle function.

Here is a sample:

``````from manim import *

class RightAngleExample(Scene):
def construct(self):
line1 = Line( LEFT, RIGHT )
line2 = Line( DOWN, UP )
rightangles = [
RightAngle(line1, line2),
RightAngle(line1, line2, length=0.4, quadrant=(1,-1)),
RightAngle(line1, line2, length=0.5, quadrant=(-1,1), stroke_width=8),
RightAngle(line1, line2, length=0.7, quadrant=(-1,-1), color=RED),
]
line_list = VGroup( *[VGroup() for k in range(4)] )
for k in range(4):
linea = line1.copy()
lineb = line2.copy()
line_list[k].add( linea )
line_list[k].add( lineb )
line_list[k].add( rightangles[k] )
line_list.arrange_in_grid(buff=1.5)
self.add(
line_list
)
``````
