Triangle Theorems Calculator Triangle Shape (ASA) A = angle A B = angle B C = angle C a = side a b = side b c = side c P = perimeter s = semi-perimeter K = area r = radius of inscribed circle R = radius of circumscribed circle Triangle Theorems: Each calculation option, shown below, has sub bullets that list the sequence of methods used in this calculator to solve for unknown angle and side values including Sum of Angles in a Triangle, Law of Sines and Law of Cosines. These are NOT the ONLY sequences you could use to solve these. AAA is Angle, Angle, Angle - given the sizes of 2 angles of a triangle you can calculate the size of the third angle. SAS is Side, Angle, Side - given the size of 2 sides (c and a) and the size of the angle B that is in between those 2 sides you can calculate the sizes of the remaining 1 side and 2 angles. Sum of Angles in a Triangle In Degrees A + B + C = 180° In Radians A + B + C = π Law of Sines a/sin A = b/sin B = c/sin C Solving, for example, for an angle, A = sin-1 [ a*sin(B) / b ] Dr.

Worksheets, Lesson Plans, Teacher Resources, and Rubrics from TeAch-nology.com Soft Start to Khan Academy in your Classroom | Comundo Khan Academy has grown so much and it has so many entry points and options that a teacher starting to use it may feel overwhelmed. Because Khan Academy is an online application with feedback to the student and teacher, it is a perfect blended learning option. However, blended learning also offers many different models. But for now, your first question is: Where do I start? But how do you select appropriate Khan Academy activities for your students? Select Khan Activities for your Students: The first step for you as a teacher is to select which activities are appropriate for your students, specially because Khan Academy allows adapting to the individual student’s needs. Use MAP Test Correlation to Khan Academy: MAP test now has what they call the Learning Continuum, which is a really cool feature that unpacks each RIT range by describing the corresponding skills. Use Khan Knowledge Map: In Khan Knowledge Map you can search a topic and see related concepts and skills. Khan Academy Missions:

Pythagorean Theorem Word Problems 1A 10 m long ladder is leaning against a wall. The bottom of the ladder is 6 m from the base of where the wall meets the ground. At what height from the ground does the top of the ladder lean against the wall? 2Determine the side of an equilateral triangle whose perimeter is equal to a square of side 12 cm. Are their areas equal? 3Calculate the area of an equilateral triangle inscribed in a circle of radius 6 cm. 4Determine the area of the square inscribed in a circle with a circumference of 18.84 cm. 5A square with a side of 2 m has a circle inscribed in it and in turn this circle has a square inscribed in it. 6The perimeter of an isosceles trapezoid is 110 m and the bases are 40 and 30 m in length. 7A regular hexagon of side 4 cm has a circle inscribed and another circumscribed around its shape. 8A chord of 48 cm is 7 cm from the center of a circle. 9The legs of a right triangle inscribed in a circle measure 22.2 cm and 29.6 cm.

untitled An axiom is an established or accepted principle. For this section, the following are accepted as axioms. A theorem is a hypothesis (proposition) that can be shown to be true by accepted mathematical operations and arguments. A proof is the process of showing a theorem to be correct. The converse of a theorem is the reverse of the hypothesis and the conclusion. Given \(OQ \perp PR\) and \(PR = 8\) units, determine the value of \(x\). Use theorems and the given information to find all equal angles and sides on the diagram \(PQ = QR = 4 \qquad (\perp \text{ from centre bisects chord})\) Solve for \(x\) In \(\triangle OQP\): \[\begin{array}{rll} PQ &= 4 & (\perp \text{ from centre bisects chord}) \\ OP^2 &= OQ^2 + QP^2 & (\text{Pythagoras}) \\ 5^2 &= x^2 + 4^2 & \\ \therefore x^2 &= 25 - 16 & \\ x^2 &= 9 & \\ x &= 3 & \end{array}\] Write the final answer \(x = 3\) units. In the circle with centre \(O\), \(OQ \perp PR\), \(OQ = 4\) units and \(PR=10\). Solve for \(a\) Conclusion Cyclic quadrilaterals
