Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane

Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
Measure the angle in a plane perpendicular to the axis of rotation, between the position of a fixed point at the start and end of the rotation.

Cjic
a closed plane figure with all sides congruent and all all angles
A right angle triangle is a plane figure not a 3d one.
An isosceles triangle and an equilateral triangle
The exterior angle of a regular n-sided plane figure is 360/n degrees, in this case 51.29 degreesImproved Answer:360/7 = 51.42857143 or 51.43 degrees to 2 decimal places.
TWO SHAPES THAT ARE THE SAME SIZE AND SAME SHAPE ARE CONGRUENT. THEY CAN BE TURNED OR ROTATED ANY DIRECTION. POLYGONS AND ANY OTHER SHAPES CAN BE CONGRUENT. LOOK AROUND YOU, YOU'LL FIND MANY CONGRUENT FIGURES. PLANE FIGURES HAVE TO BE ON PAPER OR A FLAT AREA LIKE A PICTURE. THEY ARE TWO DIMENSIONAL. :)
right angle
An angle on the coordinate plane
It area.
360° (or 2π) minus the interior angle (in Euclidean - plane - geometry)
