Which concept can be used to prove that the diagonals of a parallelogram bisect each other?
Congruent triangles: Take a parallelogram PQRS. Draw in the diagonals PR and QS. Let the point where the diagonals meet be M, Consider one pair of the parallel sides, PS and QR, say. Consider angles PSQ and RQS: As PS and QR are parallel they are equal (Z- or alternate angles). Now consider angles SPR and QRP: As PS and QR are parallel they are equal (z- or alternate angles). As PS and QR are opposite sides of a parallelogram they are equal in length; thus the triangles PMS and RMQ are congruent (Angle-Angle-Side). As the two triangle are congruent, equivalent sides are equal in length. Thus QM is the same length as MS and PM is the same length as MR As QM is the same length as MS and QMS lie on a straight line, M must be the mid point of QS, ie the diagonal PQ bisects the diagonal QS Similarly PM is the same length as MR and PMR lie on a straight line, thus M must be the mid point of PR, ie the diagonal QS bisects the diagonal PR Therefore the diagonals of a parallelogram bisect each other.
In triangle pqr qx perpendicular pr and py perpendicular qr. if pq10cm qr8cm and pr5.6cm find the length of py where qx 7.2cm?
There is a problem with your question: If pq = 10 cm, qr = 8 cm and pr = 5.6 cm then if qx is perpendicular to pr through q it does NOT equal 7.2 cm; it is approx 8.0 cm: Let X be the distance px, then xr = 5.6 - X Using Pythagoras: In pxq: 10² = qx² + X² → qx² = 10² - X² In rxq: 8² = qx² + (5.6 - X)² → qx² = 8² - (5.6 - X)² → 10² - X² = 8² - (5.6 - X)² → 10² - X² = 8² - 5.6² + 2×5.6×X - X² → 2×5.6×X = 10² - 8² + 5.6² → X = (10² - 8² + 5.6²)/(2×5.6) → qx² = 10² - ( (10² - 8² + 5.6²)/(2×5.6) )² → qx = √(10² - ( (10² - 8² + 5.6²)/(2×5.6) )²) ≈ 7.989265 cm ≈ 8.0 cm Similarly, for py: py = √(10² - ( (10² - 5.6² + 8²)/(2×8) )²) ≈ 5.59248 cm ≈ 5.6 cm The obtuse triangle has angles: qpr ≈ 53°, prq ≈ 93°, rqp ≈ 34°; the perpendiculars qx and py lie outside the triangle; angle prq ≈ 93° which is not far off a right angle making sides pr and qr approximately perpendicular, and shows that the perpendiculars to the sides next to it (ie the perpendiculars to pr and qr) will be approximately equal to the lengths of the other side (next to it, ie length of perpendicular to pr will be approx qr, and the length of the perpendicular to qr will be approx pr).
What is the probability of obtaining 4 ones in a row when rolling a fair six sided die?
The following is the probability of obtaining 4 ones IN THE FIRST FOUR rolls of a fair die. Pr(4 1's) = Pr(1)*Pr(1)*Pr(1)*Pr(1) since the events are independent. Pr(4 1's) = Pr(1)4 = (1/6)4 = 1/1296 = 0.000772

How do you prove rhs congruence?
Here is the answer to your query. Consider two ∆ABC and ∆PQR. In these two triangles ∠B = ∠Q = 90�, AB = PQ and AC = PR. We can prove the R.H.S congruence rule i.e. to prove ∆ABC ≅ ∆PQR We need the help of SSS congruence rule. We have AB = PQ, and AC = PR So, to prove ∆ABC ≅ ∆PQR in SSS congruence rule we just need to show BC = QR Now, using Pythagoras theorems in ∆ABC and ∆PQR Now, in ∆ABC and ∆PQR AB = PQ, BC = QR, AC = PR ∴ ∆ABC ≅ ∆PQR [Using SSS congruence rule] So, we have AB = PQ, AC = PR, ∠B = ∠Q = 90� and we have proved ∆ABC ≅ ∆PQR. This is proof of R.H.S. congruence rule. Hope! This will help you. Cheers!!!

Triangle pqr is an isosceles triangle in which pq equals pr equals 5cm it is circumscribed about a circle prove that qr is bisected at point of contact?
Suppose the circle meets QR at A, RP at B and PQ at C. PQ = PR (given) so PC + CQ = PB + BR. But PC and PB are tangents to the circle from point P, so PC = PB. Therefore CQ = BR Now CQ and AQ are tangents to the circle from point Q, so CQ = AQ and BR and AR are tangents to the circle from point R, so BR = AR Therefore AQ = AR, that is, A is the midpoint of QR.

How PQRS is a cyclic quadrilateralPQ7cmQR8cmPR7.5cm calculate PSR hence if SRspcalculate SPRcorrect to the nearest tenth of a degree?
To determine the measure of angle PSR in cyclic quadrilateral PQRS, we can use the Law of Cosines. First, we find angle QPR using the Law of Cosines: cos(QPR) = (QR^2 + PR^2 - PQ^2) / (2 * QR * PR). Next, we find angle PSR by subtracting angle QPR from 180 degrees since the sum of opposite angles in a cyclic quadrilateral is 180 degrees. Finally, we can find angle SPR by subtracting angle PSR from 180 degrees. Calculating these angles will give us the required measurements.
What does Tire size 10.00-20-14PR mean?
10 inch is the max width of the tyre in inflated condition. and we can use 20 inch rim for this tyre. 14 pr is denotes the plyrating. the more is pr, the more is the toughness and puncture resistant
Theory of BPT theorem?
Basic Proportionality Theorem says: If a line is drawn parallel to one side of the triangle to intersect the other two sides at distinct points .Then the other two sides are divided in the same ratio. PROOF ( to follow this proof, just draw the triangles and segments) Draw triangle PQR and construct line L parallel to segment QR. Line L intersects segment PQ and segment PR at S and T respectively. We want to show that length of PS/ length of QS is equal to length PT/ length of PR since that is what the BPT says. Construct segments SR and QT. Look at triangles PTS and QTS and note they have the same height which implies that the area of triangle PTS/ area of triangle QTS is equal to PS/ SQ. By the same reasoning, the areas of triangle SPT/ triangle SRT is equal to PT/TR. Triangles QTS and SRT both have the same height and both have ST as a base segment so they have the same area. So the ratio of the area of triangle PTS to the area of triangle QTS is equal to the ratios of the area of triangles SPT/SRT. So the ratio of PS/SQ is equal to PT/TR Since line L which is parallel to segment QR divides segment PQ and segment PR in the same ratio we have proved the BPT.
