Answer:- Equilateral triangle has an order 3 rotational symmetry.
Explanation:-
In geometry, a figure has rotational symmetry if it moves onto itself under rotation about an angle at center of rotation.
The order of rotational symmetry is the number of times the shape moves onto itself throughout a rotation of 360°.
An equilateral triangle has all its sides equal with equal interior angle of 60°.
It moves onto itself three times throughout a rotation of 360°.
⇒Equilateral triangle has an order 3 rotational symmetry.
Answer:
<QRS= (10.x - 1) = (10.6 - 1) = 59°
Step-by-step explanation:
the triangle is not accurate but drawing one is truly useful in calculating. Besides, I don't know how it is called in English but it is something about the exterior angles (maybe)
The in cline of the ramp is 7.2
Answer:
117
Step-by-step explanation:
Answer:
Scalene, right triangle
Step-by-step explanation:
its a scalene triangle because all the sides are different, and a right triangle because the box in the corners is what shows whether the angle is a right angle or not.
Hope that makes sense.
