Triangle Construction Techniques and Concepts

This video tutorial teaches how to construct three types of triangles: one with three given sides, one with one side and two angles, and one with two sides and one angle. It provides step-by-step instructions, including the necessary equipment such as a ruler, protractor, and compass. The tutorial emphasizes the importance of labeling and accuracy in construction.

What is the main focus of the video tutorial?

• Solving triangle equations

• Learning about triangle properties

• Constructing different types of triangles

• Understanding triangle theorems

Which of the following is NOT required for constructing triangles in this tutorial?

• Calculator

• Compass

• Protractor

• Ruler

What is the first step in constructing a triangle given the lengths of three sides?

• Draw any side as the base

• Draw the middle side as the base

• Draw the longest side as the base

• Draw the shortest side as the base

How do you use the compass to draw arcs for the triangle construction?

• Open the compass to the length of one side and draw an arc

• Open the compass to the length of the hypotenuse

• Open the compass to the length of the base

• Open the compass to any random length

What should you do after constructing the triangle with three sides?

• Erase the arcs

• Label the sides with their lengths

• Draw another triangle

• Measure the angles

When constructing a triangle with one side and two angles, what is the first step?

• Draw any side

• Draw the shortest side

• Draw the given side as the base

• Draw the longest side

How do you determine which scale to use on the protractor?

• Always use the inside scale

• Always use the outside scale

• Use the scale that starts at zero

• Use the scale that starts at 180

What should you do after drawing the angles for the second triangle?

• Erase the base

• Label the angles

• Measure the sides

• Draw another angle

What is the first step in constructing a triangle with two sides and one angle?

• Draw any side as the base

• Draw the given angle

• Draw the shortest side as the base

• Draw the longest side as the base

How do you use the protractor to draw the given angle?

• Use the scale that starts at zero

• Use the scale that starts at 180

• Use any scale

• Use the scale that starts at 90
