I need help with Lesson 2: Parallel Lines and Angles and Lesson 3: Congruent Polygons

OpenStudy (31356):

Do you take Geometry or Algebra?

OpenStudy (anonymous):

Yes

OpenStudy (31356):

Which one?

OpenStudy (anonymous):

Algebra

OpenStudy (31356):

Cool, me too

OpenStudy (anonymous):

If u give me the answer for Lesson 2: Parallel Lines and Angles and Lesson 3: Congruent Polygons I'll give u a metal

OpenStudy (31356):

What is your answer?

OpenStudy (31356):

Or question?

Linear Pair Conjecture If two angles form a linear pair, then the measures of the angles add up to 180°. (Lesson 2.5) C-2 Vertical Angles Conjecture If two angles are vertical angles, then they are congruent (have equal measures). (Lesson 2.5) C-3a Corresponding Angles Conjecture, or CA Conjecture If two parallel lines are cut by a transversal, then corresponding angles are congruent. (Lesson 2.6) C-3b Alternate Interior Angles Conjecture, or AIA Conjecture If two parallel lines are cut by a transversal, then alternate interior angles are congruent. (Lesson 2.6) C-3c Alternate Exterior Angles Conjecture, or AEA Conjecture If two parallel lines are cut by a transversal, then alternate exterior angles are congruent. (Lesson 2.6) C-3 Parallel Lines Conjecture If two parallel lines are cut by a transversal, then corresponding angles are congruent, alternate interior angles are congruent, and alternate exterior angles are congruent. (Lesson 2.6) C-4 Converse of the Parallel Lines Conjecture If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel. (Lesson 2.6) Chapter 3 C-5 Perpendicular Bisector Conjecture If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints. (Lesson 3.2) C-6 Converse of the Perpendicular Bisector Conjecture If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of the segment. (Lesson 3.2) C-7 Shortest Distance Conjecture The shortest distance from a point to a line is measured along the perpendicular segment from the point to the line. (Lesson 3.3) C-8 Angle Bisector Conjecture If a point is on the bisector of an angle, then it is equidistant from the sides of the angle. (Lesson 3.4) C-9 Angle Bisector Concurrency Conjecture The three angle bisectors of a triangle are concurrent (meet at a point). (Lesson 3.7) C-10 Perpendicular Bisector Concurrency Conjecture The three perpendicular bisectors of a triangle are concurrent. (Lesson 3.7) C-11 Altitude Concurrency Conjecture The three altitudes (or the lines containing the altitudes) of a triangle are concurrent. (Lesson 3.7) C-12 Circumcenter Conjecture The circumcenter of a triangle is equidistant from the vertices. (Lesson 3.7) C-13 Incenter Conjecture The incenter of a triangle is equidistant from the sides. (Lesson 3.7) C-14 Median Concurrency Conjecture The three medians of a triangle are concurrent. (Lesson 3.8) C-15 Centroid Conjecture The centroid of a triangle divides each median into two parts so that the distance from the centroid to the vertex is twice the distance from the centroid to the midpoint of the opposite side. (Lesson 3.8

Ok

OpenStudy (31356):

Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Just remember: Always the same distance apart and never touching. When parallel lines get crossed by another line (which is called a Transversal), you can see that many angles are the same.

Thx for the medal! :)

OpenStudy (31356):

Definition: Polygons are congruent when they have the same number of sides, and all corresponding sides and interior angles are congruent. The polygons will have the same shape and size, but one may be a rotated, or be the mirror image of the other.

OpenStudy (31356):

That is for congruent polygons

OpenStudy (anonymous):

Do u know know the answers forthe tezt Lesson 3: Congruent Polygons

OpenStudy (31356):

No

OpenStudy (31356):

What are the question?

OpenStudy (anonymous):

To many to type
