Let us choose a point on the shape and transform it. Hence, the scale factor of the dilation is 0.5. Also, the shadow XYZ is an enlarged image of the object XYZ. Lines AC (or q) and BD (or p) are called diagonals The line perpendicular to lines AD & BC is called the height or altitude. Curriculum alignment. Manage Settings An everyday use of triangle math is if you want to lay tiles at perfect 90 or 45 to the sides of a room. Step 1 : Use the coordinates to find the lengths of the sides of each triangle. In the displayed triangles, the lengths of the sides are given by A = 48 mm, B = 81 mm, C = 68 mm, and a = 21 mm. Reduction: If there is any contraction in the size of the image after you perform dilation, then it is said to be a reduction. Similarly, in the figure The calculator can be used to calculate applicatons like the number of bricks in a wall the number of rectangular cuts possible from a steel or plywood plate Input the large rectangle inside dimensions - and the outside dimensions of the smaller rectangles. Since the scale factor is thesame for all correspondingsides, we can record just apair of side lengths. Items included with question papers. The scale factor is the ratio of alength of the image to the corresponding length on the original figure. Materials required for examination. triangle X Y Z. All three internal angles are congruent to each other, and all of them are equal to 60. Enter the dimensions of the actual object (or measurements of the scaled object if you are planning on converting a scale to an actual size) 4. Solution: Let X Y X Y = Y Z Y Z = Z X Z X = k. (i) X Y X Y = k. X Y 4 c m = 3 X' Y' = 3 4 X' Y' = 12 (ii) Y Z Y Z = k. 7.5 Y Z = 3 YZ = 7.5 c m 3 YZ = 2.5 cm 2.
