What allows a figure to remain congruent as it rotates around a point in its plane?
Rigidity.
What is a closed plane figure with 4 congruent sides and 4 right angles?
Cjic
What is the measure of the third exterior angle if Two exterior angles of a triangle have measures of 110 degrees and 100 degrees?
Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
How do you find the angle of rotation?
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.
What is a similar plane figure?
It is a figure that is the same as another figure in the plane. A square is the same plane figure as another square, but a cube is same the same plane figure even tho it is made up of 6 squares.
What is a closed plane figure with all sides and the angles congruent?
A closed plane figure with all sides and angles congruent is known as a regular polygon. Examples include regular triangles (equilateral triangles) and regular quadrilaterals (squares). In a regular polygon, each side is of equal length, and each interior angle has the same measure. This symmetry gives regular polygons their distinctive geometric properties.
Does the angle measure increase by 90 deg if a figure is rotated 90 deg counterclockwise?
No, the angle measure of a figure does not increase by 90 degrees when it is rotated 90 degrees counterclockwise. Instead, the orientation of the figure changes, but the measures of its angles remain the same. The rotation simply affects the position of the figure in the plane, not the size or measure of its angles.

Rigidity.
What is a closed plane figure with 4 congruent sides and 4 right angles?
Cjic
What is the difinition of a polygon?
a closed plane figure with all sides congruent and all all angles
What is a plane figure with at least two congruent sides and three vertices?
An isosceles triangle and an equilateral triangle
How do you get the volume of a 3d right angle triangle?
A right angle triangle is a plane figure not a 3d one.
What is a Congruent plane figure?
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. :)
What is the measure of exterior angle of heptagon?
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.
What is A plane figure made up of sides joined at endpoints?
right angle
What figure is formed by a terminal side and an initial side?
An angle on the coordinate plane
The measure of an exterior angle of a triangle is?
360° (or 2π) minus the interior angle (in Euclidean - plane - geometry)
