5. Assume Euclidean geometry. Prove the following: if a trapezoid has congruent legs i.e. the non-parallel sides have the same length), then the angles at the base of the trapezoid are congruent 6.Assume Euclidean geometry. Let ABCD be a trapezoid with ADI BC and with AB-AD. Show that BD bisects angle LABC. 5. Assume Euclidean geometry. Prove the following: if a trapezoid has congruent legs i.e. the non-parallel sides have the same length), then the angles at the base of...

euclidean geometry step by step process 1. (7 pts) Prove that the diagonals of a rectangle are congruent. 2. (18 pts) In the diagram below, prove that M is the midpoint of AC and BD if and only if ABCD is a parallelogram. 3. (9 pts) Use #1 and #2 above to prove that the diagonals of a square cut each other into 4 congruent segments. Use #3 to prove that the diagonals of a square are angle bisectors of...
For two intersecting lines, angle 1 and angle 2 are a pair of vertical angles formed. Given that and , find the value of x . PLEASE EXPLAIN IN DETAIL EVERY STEP BECAUSE I REALLY WANT TO UNDERSTAND. THANK YOU ! + mZ1 = m/2 =
2) (i) State the converse of the Alternate Interior Angle Theorem in Neutral Geometry. (ii) Prove that if the converse of the Alternate Interior Angle Theorem is true, then all triangles have zero defect. [Hint: For an arbitrary triangle, ABC, draw a line through C parallel to side AB. Justify why you can do this.] 5) Consider the following statements: I: If two triangles are congruent, then they have equal defect. II: If two triangles are similar, then they have...
do the problem no 1 Let r, r2 Tm be a given set of positive rational numbers whose sum is 1. Define the function f by f(n) = n - nfor each positive integer n. Determine the minimum and maximum values of f(n) k=1 An acute angle XCY and points A and B on the rays CX and CY, respectively, are given such that |CX| < \CA = |CB| < \CY].

The complement of an acute angle is an obtuse angle. 6. An angle bisector in...
Moment for Discovery SSS Theorem Via Kites and Darts Two geometric figures, the kite and dart, though elementary, are quite useful. The figures we have in mind are shown in Figure 3.26, where it is assumed that AB = AD and BC = CD. The dart is distinguished from the kite by virtue of the eight angles at A, B, C, and D involving the diagonals AC and BD being either all acute angles (for the kite), or two of...
