What is required for two triangles to be similar?
If ll the angles of one triangle are the same as the angles of another triangle they are similar. Rotation is always allowed and mirroring often can be allowed.
What fraction of a full rotation is 60 degrees?
One-sixth
List the first 8 angles of rotation for a regular polygon that has 20 sides?
If you rotate a 20-sided regular polygon by 360/20 degrees, the result will look the same as the original polygon. Any additional rotation will be a multiple of this number.
What is the image of point (3 5) if the rotation is -90?
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
What are the different types of angles in a circle?
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.
What is the sum of the interior angle measures of a 15gon?
S of interior angles of ANY n-sided polygon is (2n -4) right angles, so 2 x 30 - 4 = 56, 56 x 90 = 5040 degrees
How many angles of rotation does an octagon have?
An octagon may have 1, 2, 4 or 8 angles of rotation.
What is a full rotation in angles?
360⁰
What are the Three transformations in angles?
The three transformation in angles are translation , rotation , reflection .
How many right angles are in 1 complete rotation?
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.
Which benchmark angles multiples of 30 and 45 are the closest to the rotation angles below?
45
How many right angles are there in a full rotation?
4
How many right angles in a full rotation?
A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
What are all right angles?
Right angles are ninety degree angles. That is equal to one quarter of a complete rotation.
How many angles of rotation does a pentadecagon have?
A Pentadecagon had 15 sides
Standard methods of measuring angles?
1/3 rotation counterclockwise
How are translation and rotation the same?
They do not alter the size nor the angles of the shape.
