You will use this wiki to keep track of all our vocabulary words for the year. Here is what needs to go into the wiki for each entry:

  • You will need to include the vocabulary word.
  • You will need to type the true definition.
  • You will need to type your own definition.
  • You will need to include a picture to demonstrate the word
  • You will need to create a video that goes with that word.


A

Altitude of a Triangle
Derek Cook
definiton: the perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side.
My definition: a segment that starts from the vertex and is perpendicular to the opposite side.

Angle Bisector Theorem(5.5)

Parker Archuleta
Definition: If a point is on the bisector of an angle, then it's equidistant from the two sides of the angle.
My Definition: If you have a point on the angel bisector, then that point is an equal distance from the two sides of the angle.

Concurrency of Angle Bisectors of a Triangle (Theorem 5.7)

By: Katie Brauck

mann

Definition: the angle bisectors of a triangle intersect at a point that is equidistant from the sides of the triangle.
My Definition: if you take the incenter of a triangle, then that point will be equal distances from each side of the triangle

Converse of Angle Bisector Theorem (Theorem 5.6)

by Robin Bai


Textbok Definition: If a point is in the interior of an angle and is equidistant from the sides of the triangle, then it lies on the bisector of an angle.

My definition: If the two line segments are congruent to each other and both are perpendicular to the sides of the angle, then the ray bisects the angle.

Converse ofthe hinge theorem:

Definition: If two sides of one triangle are congruent to two sides of another triangle, and the third side of the firstis longer than the third side of the second, then the included angle of the first is largerthan the included angle of the second.


My Definition: If theres two traingles and two of thier sides are congruent then the third included angle that is larger is the greatest angle.

Hinge Theorem

Definition- If two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second then the third side of the first is longer than the third side of the second.

My Definition- If two sides of one triangle are congruent to two sides of another triangle, and the angle measures in between them are different then the one with the bigger angle is one with the biggest side.

‍Midsegment of a Triangle- by Erin Krist

My Definition- When the midpoints of sides of a triangle are connected by a segment.
Book Definition- A segment that connects the midpoints of two sides of the triangle.

Perpendicular Bistector Theorem (theorem 5.2)

Book Definition- In a plane, if a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.

My Defention- If a point is on a Perpendicular bisector of a segment, it is the same distance from the endpoints of a segment.

Theorem 5.3- by Alex Zhou

Textbook Definition: In a plane, if a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of that segment.

My Definition: On a plane, if any point is the same distance from each endpoint of a line segment, then it lies on the perpendicular bisector of that segment.

Theorem 5.10
Sarah Lewis ;)

Definition: If one side of a triangle is longer than another side, then the angle opposite the
longer side is larger than the angle opposite the shorter side.
My Definition: Longer side-->opposite angle is the largest.
Shorter side--> opposite angle is the shortest.

Triangle Inequality Theorem

by: Hunter McManus

Definition: The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

My Definition: If you add the lengths of two sides of a triangle the sum is always greater than the length of the third side.

Theorem 5.11

by Rachel Lucas

Definition: If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.

My Definition: If there is an angle longer than the others, then the side opposite it is also longer than the others.
Picture:triangle.jpeg BC is opposite <A which is the greatest angle, making BC the greatest side.
