hint for d): consider a point D such that M is the midpoint of CD. Which segments are congruent here? Do you see a triangle with all three side lengts given.
Could you please write some instructions on the side so I know how to follow your solution?

I need help doing a doing two column for these two
propositions.
Book 1 Proposition 7:
Given two straight lines constructed from the ends of a straight
line and meeting in a point, there cannot be constructed from the
ends of the same straight line, and on the same side of it, two
other straight lines meeting in another point and equal to the
former two respectively, namely each equal to that from the same
end.

520. Given triangle ABC, let F be the point where segment BC meets the bisector of angle BAC, Draw the line through B that is parallel to segment AF, and let E be the point where this parallel meets the extension of segment CA. (a) Find the four congruent angles in your diagram. (b) How are the lengths EA, AC, BF, and FC related? (c) The Angle-Bisector Theorem: How are the lengths AB, AC, BF, and FC related?

QUESTION 1 Let P be a point inside A ABC. Suppose D is the midpoint of AB, E is the midpoint of BC, and F is the midpoint of CA. If PĎ is perpendicular to AB and PE is perpendicular to BC, then PF is perpendicular to CÃ as well. Additionally, make a sketch of a picture labeling all points to illustrate the described setting. In your explanation you can use All Axioms of Incidence, Order, and Congruence and Theorems...

535. Suppose that ABCD is a parallelogram, in which AB- 2BC. Let M be the midpoint of segment AB. Prove that segments CM and DM bisect angles BCD and CDA, respectively. What is the size of angle CMD? Justify your response. from you toward the sun. How high is the sun in the sky? 541. Hexagon ABCDEF is regular. Prove that segments AE and ED are perpendicular. 549 Suppose that PORS is a rhombus with PO-12 and...
Recall the following definitions Two angles are called supplementary if they share a side and the other two sides are opposite rays. The segment PR is called the sum of segments AB and CD if there exists a point Q on the segment PR (i.e. on the line PR between P and R) such that segment PQ is congruent to segment AB and segment QR is congruent to segment CD In a similar way, give a definition of: (a) vertical...
2. Consider a triangle ABC. Let M denote the midpoint of side AC. If BM - AM, show that angle B is a right angle. (10 points)
Let A, B, C be three collinear points and let D, E, F be the midpoints of segments AB, BC, and AC, respectively. Prove that the segments DE and BF have the same midpoint. Let d be a line and let A, B, C be three points not on d. Prove that if d does not separate points A and B and it does not separate points B and C, then it does not separate points A and C.

nat you ho has cheated on this exam. 1. Let AABN and AA'B'Y by asymptotic triangles. Prove that if LABN 2 ZA'B'Y and AB> ΑΒ , then /BAΩ< ΒA. 2. Let AABC be an ordinary triangle and let D be any point of the interior. Prove that the sum of the angles of AABD is greater than the sum of the angles of AABC. 3. Suppose that two lines & and m have a common perpendicular MN. Let A...
am i correct?
Select ALL TRUE statements. For the given AABCand points L, M, and N that are the points at which the incircle touches the sides BC, AC, and AB respectively, the lines AL, BM, and CN are concurrent. Bisector of an interior angle of a triangle and the bisectors of the remote exterior angles are concurrent. A proper Cevian line contains any two points of the given triangle ABC. The interior angle bisectors of an acute triangle are...
