Mastering Small Basic Drawing and Math

How do you use the Drawline method to create a triangle?

• Draw a circle around three points to create a triangle.

• Connect two points with a line to form a triangle.

• Draw a single line to represent the triangle's base.

• Draw three lines connecting three points to form a triangle.

What are the coordinates needed to draw a rectangle using Drawline?

• Coordinates: (0, 0), (1, 1)

• Coordinates: (x1, y1), (x2, y1)

• Coordinates: (x1, y1), (x1, y2)

• Coordinates: (x1, y1), (x2, y2)

Write a Small Basic code snippet to find the sum of three numbers.

• num1 = 5; num2 = 10; num3 = 15; sum = num1 - num2 - num3; TextWindow.WriteLine(sum);

• num1 = 5; num2 = 10; num3 = 15; sum = num1 * num2 * num3; TextWindow.WriteLine(sum);

• num1 = 5; num2 = 10; num3 = 15; sum = num1 + num2 + num3; TextWindow.WriteLine(sum);

• num1 = 5; num2 = 10; sum = num1 + num2; TextWindow.WriteLine(sum);

How can you calculate the average of three input values in Small Basic?

• average = (value1 + value2 + value3) / 3

• average = (value1 + value2 + value3) * 3

• average = (value1 - value2 - value3) / 3

• average = (value1 + value2) / 2

What is input validation and why is it important when taking user input?

• Input validation slows down the user input process.

• Input validation is crucial for ensuring data integrity and security when taking user input.

• Input validation is irrelevant for secure applications.

• Input validation is only necessary for numeric data.

Describe how to draw a triangle using three Drawline commands.

• Drawline(A, B), Drawline(A, C), Drawline(B, C) will create a triangle.

• Use Drawline(A, C), Drawline(C, B), Drawline(B, A) to draw a triangle.

• Drawline(A, B), Drawline(A, A), Drawline(B, C) to form a triangle.

• Use Drawline(A, B), Drawline(B, C), Drawline(C, A) to draw a triangle.

How can you combine shapes using the Drawline method?

• Use the DrawLine method to connect the vertices of the shapes.

• Use the DrawLine method to fill the shapes with color.

• You cannot combine shapes using the DrawLine method.

• DrawLine can only be used for straight lines, not shapes.

What is the formula for finding the sum of two numbers in Small Basic?

• sum = a - b

• sum = a + b

• sum = a * b

• sum = a / b

How do you ensure that user inputs are valid numbers in Small Basic?

• Convert the input to an integer without validation.

• Check if the input is a non-empty string.

• Use the 'IsString' function to validate user inputs.

• Use the 'IsNumber' function to validate user inputs.

Explain how to draw a rectangle with specific dimensions using Drawline.

• Draw a circle with the same width and height.

• Connect the midpoints of the sides to form a rectangle.

• Use Drawline to create a triangle with the specified dimensions.

• Use Drawline to connect the four corners of the rectangle based on the specified width and height.
