Find the length of side AB and AC. 45° c. 39° d. 51° e. 12° Short Answer Use the diagram to indicate the measure. Construct Arguments Write a two-column proof for the Angle Bisector Theorem. Precisely explain the steps for dilating point F using the same center and a scale factor of 6. A rectangle is 16 m by 9 m. Find a side of the square whose area equals the area of the rectangle. If from the same wire, he builds a rectangle with a width of 6 … B) AABF and ACDE are equilateral triangles ABF = 6 cm and BC = 8 cm.Find the area of the given figure Get the answers you need, now! 2. 9. 0.058 b. Given that ∠ACF ≅ ∠ECFand m∠ABF = m∠EDF = 90, write a two-column proof to show that ABF ≅ EDF. The perpendicular bisectors of ABC meet at point D. Find BD. 35 c Verbally opposite are ; a / r C) —3 S 75 70 les (Total for Question 3 is 4 marks) p 49308 A 0 420 350 750 . With our perimeter of a triangle calculator you can easily calculate the perimeter of that figure. Now, Perimeter = 2(l + b) = 2 (162 + 90) = 2(252) = 504 m. Therefore, cost for fencing the surrounding 504 m at the rate of ₹3.25 per metre = ₹(504 × 3.25) = ₹1638. 90° b. The tool has the basic formula implemented - the one assuming you know all three triangle sides. Find the perimeterof the figure… Answers: 3 Get Other questions on the subject: Mathematics. Show that angle ABF = 700 Give a reason for each stage of your working. 34 cm. perimeter of ABC is 23, what is the perimeter of ABE? 27. 28. If the perimeter is 30 cm, then its width is cm. The perpendicular bisectors of ABC meet at point D. Find DC. In ABC, if m ABF = 39° and BF is an angle bisector, find m BCE. 10. Therefore, BF = CE ( by CPCT) Problem 2: Given an ∆ABC whose perimeter is 13 cm and ∠ABC = ∠ACB and length of side BC equals 3 cm. Its perimeter is cm. So, ∆ABF ≅ ∆ACE (SAS rule) Since, If two triangles are congruent, their corresponding sides are equal. 4 The diagram shows a logo made from three circles- m 3cm 3cm Each circle has centre O. Q. John builds a square with a side of 12 cm from some wire. Construct Arguments Write a paragraph proof for the Converse of the Angle Bisector Theorem. Mathematics, 21.06.2019 13:30, queenkimm26.
