"Points of Interest"
An exact location in space. It has no dimension
What is a point?
an angle whose measure is 90 degrees
What is a right angle?
Two lines that cross
What are intersecting lines?
This triangle has 3 sides that are all the same length. Because all the sides are congruent, all the sides must also have congruent angles. This requires each angle to be 60 degrees
What is an equilateral triangle?
This shape can be a rhombus and a rectangle. In this shape all the angles are congruent and all sides are congruent.
What is a square?
A collection of points along a straight path that extends endlessly in both directions
What is a line?
An angle whose measure is more than 90 degrees and less than 180 degrees
What is an obtuse angle?
An angle whose measure is less than 90 degrees
What is an acute angle?
This triangle is one that contains a 90-degree angle. This triangle has sides that meet the requirements of the Pythagorean Theorem
What is a Right triangle?
In this shape, both pairs of opposite sides are parallel, both pairs of opposite sides are congruent, Both pairs of opposites angles are congruent, consecutive angles are supplementary, and diagonals bisect each other
What is a parallelogram?
A part of a line having two endpoints.
What is a line segment?
An angle whose measure is 180 degrees
What is a straight angle?
Two lines in the same plane that do not intersect
What are parallel lines?
This triangle has 2 sides that are in the same in length. Because two sides are congruent, tow angles must also be congruent
What is an Isosceles triangle?
This shape has 1 pair of parallel sides and angles on the same "side" of the bases are supplementary.
What is a trapezoid?
A part of a line having only one endpoint
What is a ray?
If the sum of their measure is 180 degrees
When are two angles supplementary?
Two lines that intersect to form right angles.
What are perpendicular lines?
This shape has 2 consecutive pairs of congruent, 1 pair of congruent opposite angles, and diagonals perpendicular
( daily double )
What is a kite?
This is a parallelogram with all angles congruent. It also has diagonals congruent
What is a rectangle?
Consists of two rays that have a common endpoint called the vertex of the angle
What is an Angle?
If the sum of their measures is 90 degrees
When are two angles complementary?
Two angles with equal measure formed by two intersecting lines
What are vetical angles?
This triangle has 3 sides of different lengths. Because the sides are of different lengths, the angles must also be of different lengths
What is a Scalene triangle?
This shape has 1 pair of parallel sides, congruent legs, 2 pair of congruent base angles, and diagonals congruent
What is an Isosceles trapezoid?
