Marla draws a diagonal in a rhombus to form two triangles. What term can she use to classify each triangle? Explain. a. Acute; a rhombus always has 2 acute angles so the 3 angles in each triangle must all be acute. b. Equilateral; since a rhombus always has 4 equal sides, each triangle must have 3 equal sides. c. Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides. d. Obtuse; a rhombus always has 2 obtuse angles so each triangle must have an obtuse angle.

trigonometry is a field of mathematics that studies the relationships that exist between the sides of a triangle and its angles. How much do you know about the properties of triangles? Have you worked with them much in the past? These relationships and properties can be used to model many physical properties in the real world. One of these properties is called periodic motion, such as the motion made by a yo-yo going up and down. What kinds of periodic motion are you familiar with? Why might scientists and businesses be interested in tracking this type of motion using equations?

According to the given information, segment AB is parallel to segment DC and segment BC is parallel to segment AD.. Using a straightedge, extend segment AB and place point P above point B. By the same reasoning, extend segment AD and place point T to the left of point A. Angles BCD and PBC are congruent by the Alternate Interior Angles Theorem. Angles PBC and BAD are congruent by the Corresponding Angles Theorem. By the __________ Property of Equality, angles BCD and BAD are congruent. Angles ABC and BAT are congruent by the Alternate Interior Theorem. Angles BAT and CDA are congruent by the Corresponding Angles Theorem. By the __________ Property of Equality, ∠ABC is congruent to ∠CDA. Consequently, opposite angles of parallelogram ABCD are congruent. What properties accurately complete the proof?Addition Transitive Reflexive Reflexive Substitution Reflexive Transitive Transitive
