Geometry Crossword

Connects two points via the shortest path and continues indefinitely (forever) in both directions
Part of a line between two points
Line segments that never intersect (they are always the same distance apart)
An angle that measures less than 90°
An angle that measures more than 90°
A triangle with all three sides with different lengths
A triangle with two equal length sides (and two equal internal angles)
A triangle with all three sides of equal length (each internal angles = 60°)
Distance around a circle (the perimeter)
the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs
the central number in a geometric progression
An altitude of a triangle is a line segment connecting a vertex to the line containing the opposite side and perpendicular to that side.
A circle's diameter is a segment that passes through the center and has its endpoints on the circle
right triangle is the side of the triangle that is opposite to the right angle.
flat, two-dimensional object. We often represent a plane by a piece of paper, a blackboard, or the top of a desk. In fact, none of these is actually a plane, because a plane must continue infinitely in all directions and have no thickness at all. A plane can be defined by two intersecting lines or by three non-collinear points.
A point specifies only location; it has no length, width, or depth. We usually represent a point with a dot on paper, but the dot we make has some dimension, while a true point has dimension 0.
if you have a right triangle, then the square built on the hypotenuse is equal to the sum of the squares built on the other two sides. a2 + b2 = c2.
a polygon with exactly four sides.
quadrilateral with four right angles.
triangle with one right (90°) angle.
