Scale drawings of geometric figures
Scale drawing with geometric figures
Your student will learn about scaling shapes this week. If the form is extended without distorting it, the image is a scaled copy of the original. Here’s an original and five copies of a photograph. Pictures A, B, and E are not scaled copies of the original, but they are scaled copies of the original.
The sides of each scaled copy are a certain amount of times as long as the original’s corresponding sides. This number is referred to as the scale factor. The size of the scale factor has an influence on the copy size. A copy with a scale factor greater than one is larger than the original. A scale factor of less than one results in a smaller copy.
Your student will be talking about scale drawings this week. A scale drawing is a depiction of an actual entity or position in two dimensions. Scale sketches contain items like maps and floor plans.
The scale indicates what a given length on the scale drawing corresponds to in terms of actual length. A scale of “1 inch to 5 miles,” for example, indicates that 1 inch on the drawing corresponds to 5 real miles. If the drawing portrays a road that is 2 inches long, we may be confident that the road is actually 2 inches long.
Lesson 8.1 similar shapes and scale drawings
Architects and engineers often use scale drawings to design and build their designs. The ratio of the drawing size to the actual size of the item is what scale drawing is all about. As a consequence, the drawing scale is the real size.

Understanding proportional reasoning and scale drawings
Helpful videos, solutions, and lessons Students in Grade 7 learn how to solve problems involving geometric figure scale drawings, such as computing real lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
1. Vincent recommends to the Student Government that a basketball hoop be built at his school, along with a court marked with all of the shooting lines and boundary lines, for students to use during recess. He proposes the installation of a half-court style, as shown below. After consulting with school administrators, he learns that it would be accepted if it fits on the school’s empty lot, which measures 25 feet by 75 feet. Will the property be large enough for the court he envisions? Justify your role.
2. The image portrays a greenhouse. Every 20 meters, one centimeter is applied to the scale. The drawing’s squares are 1 cm by 1 cm in dimension. Based on the specified drawing, decide the actual length and width.
3. A graphic designer is working on a tablet commercial. She must enlarge the image shown here so that 0.25 inches on the scale image equals 1 inch on the actual advertising. What are the measurements of the tablet in the advertisement?
Grade 7 math 8.1a, dimensions, area, and scale drawings
Clusters should not be taught in the order in which they were sorted, from Main to Supporting. By doing so, the mathematical concepts would lose their coherence, and the potential to improve the grade’s main work with the supporting clusters would be lost.
This series of geometry challenges stresses the use of region and perimeter as students problem-solve and think while learning to code with block coding software. To complete the tasks, students will need to apply their knowledge of polygon attributes and mathematical principles of geometry. Students may explore at their own pace or collaborate on the tasks, which start out easy and progress to more complicated situations. Computer Science requirements are easily combined with math standards, offering opportunities to “Step it up!” and “Jump it up!” to improve rigor.
