Quarter 1
slides a figure without rotating or flipping it
Translation
This segment connects the midpoint of two sides of a triangle.
What is a midsegment?
How many sides does a octagon have?
8
This segment touches a circle at exactly one point.
Tangent
This triangle has all sides congruent and all angles measuring 60
equilateral triangle
flips a figure over a line of reflection without changing size and shape.
What is a reflection?
What is the centroid?
Point is where the three medians of a triangle intersect/ Center (POC)

This six-letter word starts with “radius” and ends with “diameter’s half.
Radius
This transformation turns a figure around a fixed point.
What is a rotation?
(x,y)→(−y,x)
What is the rule for a 90° CCW rotation?
What is the circumcenter?
This point is formed by the perpendicular bisectors of a triangle and is equidistant from the vertices.
figure has two parallel circular bases and a curved surface.
What is a cylinder?
Engineers use this type of triangle because it cannot change shape without changing side lengths.
rigid triangle
The longest side of a right triangle is called this.
What is the hypotenuse?

changes size but keeps the shape similar
This line divides an angle into two congruent angles.
angle bisector

This shape is never late because it always goes around in circles.
Circle
This geometric figure is always well-rounded and has no corners.
What is a circle?

Which triangle center is ALWAYS inside the triangle
Incenter
This 3D figure has two congruent circular bases and one curved lateral surface.
Cylinder
The sum of the interior angles of any triangle is always this value.
