A diagram representing a triangle RST; Angle SRT = r°, angle RTS = t° and angle TSR = s° PRTQ is a line segment; Angle PRS = x° and angle QTS = y° We need to determine. The value of x + y; As PRTQ is a line segment, we can say. x + r = t + y = 180° Therefore, x + r + t + y = 180 + 180 = 360. Or, x + y = 360 ...EXAMPLE 3 Find angle measures ALGEBRA Given that m < LKN =145° , find m <LKM and m < MKN. 2x + 10 + 4x - 3 = 145 You Try! Find the indicated angle measures. Given that m< KLM is a straight angle, find m< KLN and m <NLM. ANSWER 125°, 55° You Try! Given that m< EFG is a right angle, find m< EFH and m <HFG.And all angles are right angles: $\angle PQR = \angle QRS = \angle RSP = \angle SPQ = {90^0}$ Step 2: As the other portion $\vartriangle SRT$ is an equilateral triangle, All sides are equal: SR=RT=TS. All angles = ${60^0}$ implies $\angle SRT = \angle RTS = \angle TSR$ = ${60^0}$ Step 3: From equivalence of sides of square and triangle, PQ=QR ...Given: In right triangle ABC, right angled at C, M is the mid-point of hypotenuse AB. C is joined to M and produced to a point D such that DM = CM. Point D is joined to point B. To Prove: (i) ∆AMC ≅ ∆BMD (ii) ∠DBC is a right angle (iii) ∠DBC ≅ ∆ACB (i) In ∆AMC and ∆BMD, AM = BM | ∵ M is the mid-point of the hypotenuse ABDraw an example of each. Label the angle with its measure. Question 6. a right angle. Answer: A right angle is an angle of exactly 90° Question 7. an acute angle. Answer: The acute angle is the small angle which is less than 90°. Problem Solving. The drawing shows the angles a stair tread makes with a support board along a wall. No, not all right triangles are congruent. Considering that the sum of all the 3 interior angles of a triangle add up to 180°, in a right triangle, and that only one angle is always 90°, the other two should always add up …. 1) LL 2) HL 3) HA 4) HA 5) HA 6) Not congruent 7) Not congruent 8) LL 9) Not congruent ….Hence, the base and height of the right triangle are 6 mm each. Example 2. Calculate the right triangle’s side lengths, whose one angle is 45°, and the hypotenuse is 3√2 inches. Solution. Given that one angle of the right triangle is 45 degrees, this must be a 45°-45°-90° right triangle. Therefore, we use the n: n: n√2 ratios. Ex 6.2, 4 In the given figure, if PQ || ST, ∠PQR = 110° and ∠RST = 130°, find ∠QRS. (Hint: Draw a line parallel to ST through point R.) It is given..In this question, we are given.

The value of x + y; As PRTQ is a line segment, we can say. x + r = t + y = 180° Therefore, x + r + t + y = 180 + 180 = 360. Or, x + y = 360 ... canoe club shopdunlop tires vs michelinproduction control parameters d365maine public records
