Basic Concepts
This is a flat surface that extends into infinity.
What is Plane?
This is a type of line that lies on the y-axis of the Cartesian Plane.
What is a Vertical Line?
This is the measures for angles.
What is Degree/Radians?
This is the common endpoint of each side of a triangle.
What is/are Vertex/Vertices?
This is what quadrilaterals have that triangles don't.
What are Diagonals?
This refers to points that lie on the same plane.
What are Coplanar Points?
This is bounded by two endpoints making its length defined.
What is a Line Segment?
This angle refers to more than 180°.
What is Reflex Angle?
What is Acute Triangle?
This type of quadrilateral has equal and opposite sides, equal and opposite angles, 2 parallel sides, and 2 diagonals that bisect each other.
What is a Parallelogram?
This is "Geo" in Geometry.
What is Earth/Land?
This is the total angle of a straight line.
What is 180°?
This conjecture supports when two lines intersect, opposite angles are congruent.
What is Vertical Angle Conjecture?
What is Hypotenuse?
This is a quadrilateral that has an area of 1/2(b1+b2)h.
This can have infinitely many points making its length undefined.
What is a Line?
This is the value of x if two angles lie on a line being 4x+6 and 6x+4 respectively.
This is the supplement of the complement of 50°.
What is 140°?
This theorem states that an exterior angle is the sum of two remote interior angles.
This is the value of x in a quadrilateral ABCD, ∠DAB is 2x, ∠ABC is 3x+2, ∠BCD is 4x-4, and ∠CDA is 12-2x.
What is 50?
This is the volume of a sphere that has radius of 8 cm.
What is 2048π/3 cm³?
What are Asymptotic Lines?
This is 540° in radians. (n° x π/180° = radians)
What is 3π?
This triangle similarity theorem requires only two pairs of corresponding angles to be congruent to prove that two triangles are similar.
What is Angle-Angle Similarity Theorem?
This is the total number of degrees you'll get if you add up one exterior angle from each vertex of any quadrilateral.
What is 360°?
