Section 5.1 Classifying Triangles
A triangle is a polygon with three sides. A triangle with
vertices A, B, and C is called triangle ABC.
Classifying Triangles By Sides
Scalene Triangle: No Congruent Sides
Isosceles Triangle: At least 2 congruent sides
Section 3.7 Perpendicular Lines
Given the lines are perpendicular state everything that is
true in the diagram
In the figure OP is Perpendincular to MN and NP is
perpendicular to QS. Determine whether the each of the
following is true
Angle Relationships Created by Parallel Lines
1) Construct and Label a line with points A and B. What is the name of this line?
2) Construct and label Point C. So it is not on the current line and is to the right of it.
Section 4.2 Angles and Transversals
A transversal is a line that intersects two or more
coplanar lines at different points
Angles formed by transversals
Two angles are corresponding angles if they have
corresponding positions. For example angle 2 and
Section 4.3 Corresponding Angles Theorem
Postulate 15 Corresponding Angles Postulate:
If two parallel lines are cut by a transversal then
The measure of three of the numbered angles is 120 degrees.
Identify the angles. Explain your reasoning
Section 4.6 Write and Graph Equations of Lines
The general form of a linear equation in slope intercept form is y=mx
+B. where m is the Slope and b is the y intercept.
Write an equation of the line in slope- intercept form.
Write an equation of a line tha
Section 5.2 Angles of a Triangle
Angles: When the sides of a polygon are extended
other angles are formed.
The original angles are interior angles
Our new angles formed are the exterior angles
Theorem 4.1 Triangle Sum The
Section 8.2 -Constructing Parallelograms
We are going to first construct a parallelogram, meaning opposite sides are parallel
1) Sketch and Label point A
2) Construct Line AB through point A (Use point A as the point where you first
Segments in Circles
1) Sketch circle with center A
2) Create chord BC through the circle
3) Create chord DE, so it intersects the first chord.
4) Mark the intersection of the chords with a point and label it with F
5) Now measure the
