A scale drawing is made to enlarge a picture by using a scale factor of 3. If the Oblique Triangle Calculator (any other triangle), Circle Calculator (requires only one value). original figures, but are larger in size. In this case the SAS rule applies and the area can be calculated by solving (b x c x sin) / 2 = (10 x 14 x sin(45)) / 2 = (140 x 0.707107) / 2 = 99 / 2 = 49.5 cm2. A triangle is a polygon that has three vertices. The altitudes, the angle bisectors, the perpendicular bisectors, and the medians coincide. A scale of 1:100 means that the map distance is 100 times smaller than the real-world distance. We will discuss here about the similarity on enlargement transformation. Refresh the calculator, and type in the other parameter, e.g., perimeter. Find the scalefactor of the dilation. Hence its perimeter will be 3 8 cm = 24 cm. All three internal angles are congruent to each other, and all of them are equal to 60. Find the remaining dimensions width: 8 cm / 0.02 = 4 m, height: 5 cm / 0.02 = 2.5 m. You can evaluate the total volume of the shed so you can make sure that all your gardening equipment can fit inside: 5 m 4 m 2.5 m = 50 m. XYZ.
