Geometry Key Terms Crossword Puzzle

QUESTIONS LIST:

• line: a one-dimensional shape created from a series of points. lines have no measurement as they continue infinitely.
• point: a location. points have no shape or size.
• line segment: a portion of a line that has a definite start-point and end-point. line segments can be measured.
• ray: a portion of a line that has one definite start-point and goes on in the other direction infinitely.
• angles: created by the intersection of two rays. the intersection is called a vertex. measured by degrees.
• cosine: adjacent over hypotenuse
• sine: opposite over hypotenuse
• tangent: opposite over adjacent
• equilateral: all 3 sides and all 3 angles in a triangle are equal.
• isosceles: when 2 sides and 2 base angles in a triangle are congruent.
• angle sum theorem: the sum of angles that share a common vertex and a common side will be equal to the total angle.
• obtuse: angle that is more than 90 degrees.
• acute: angle that is less than 90 degrees.
• right: angle that is equal to 90 degrees.
• triangle inequality: the sum of the lengths of 2 sides of a triangle is greater than the length of the 3rd side and the difference of the lengths is less than the length of the 3rd side.
• parts relationship: if one side of a triangle is longer than the other side, then the angle opposite the longer side is larger than the angle apposite the shorter side.
• bisector: a line that cuts a segment or angle into 2 equal parts.
• triangle sum: all angles add up to 180 in a triangle.
• perfect square: 2 of the same numbers that when multiplied, its square root is equal to itself.
