Geometric Constructions
A geometric construction is a mathematical procedure for constructing a geometric figure from a set of given initial points, lines, and angles. The most common geometric constructions are the construction of a triangle, a square, and a regular hexagon.
Construction of Line Segment
A line segment is a part of a line that has two endpoints. The line segment can be straight or curved.
Copy of Line Segment
A line segment is a straight line that connects two points.
Construction of Angle Bisector
Given:
Angle A = 50°
Angle B = 30°
Construct the angle bisector of angle A.
The angle bisector of angle A is the line segment that bisects angle A and has its endpoints at points A and B.
How to Construct Angle Bisector`
An angle bisector is a line or ray that divides an angle into two congruent parts.
To construct an angle bisector, first draw the angle. Next, use a straight edge to draw a line through the angle that bisects it. Finally, draw two more lines perpendicular to the bisector that intersect the angle.
How to Construct A 120 Degree Angle?
There are a few ways to construct a 120 degree angle. One way is to use a compass and ruler. Draw a line segment and make a mark at each end. Turn the compass so that the point is at one end of the line and the pencil is at the other end. Draw an arc that intersects the line segment. Draw a line perpendicular to the line segment at the point where the arc intersects it. This line will be your 120 degree angle.
How to Construct A 60 Degree Angle?
There are a few ways to construct a 60 degree angle. One way is to use a protractor. Draw a line on a piece of paper and place the protractor so that the 0 degree line is on the bottom of the line. The 60 degree line will be on the top. Draw a line from the 0 degree line to the 60 degree line. Another way to construct a 60 degree angle is to use a compass. Draw a circle on a piece of paper. Draw a line from the center of the circle to the edge of the circle. The 60 degree line will be where the line intersects the circle.
How to Construct A 30 Degree Angle?
To construct a 30 degree angle, use a protractor to draw a line from the vertex of the angle to the base of the angle. Then, use the protractor to measure the angle between the line and the base of the angle.
How to Construct A 90 Degree Angle?
There are a few ways to make a 90 degree angle. One way is to use a right angle triangle. Another way is to use a protractor.
How to Construct a 45 Degree Angle?
The easiest way to construct a 45-degree angle is by using a compass and a straightedge. First, draw a line segment on your paper. Then, use the compass to draw a circle that intersects the line segment at two points. Finally, connect the two points with a straight line to form your 45-degree angle.
Facts To Remember
1. Aedes aegypti mosquitoes are the primary vectors for both Zika and chikungunya viruses.
2. These mosquitoes are found in tropical and subtropical regions worldwide.
3. Zika virus is a member of the Flaviviridae family of viruses, which also includes dengue, West Nile, and yellow fever viruses.
4. Zika virus is spread through the bite of an infected Aedes mosquito.
5. Infection with Zika virus can cause a mild illness characterized by fever, rash, joint pain, and red eyes (conjunctivitis).
6. Severe disease requiring hospitalization is uncommon, but has been reported in a small number of cases.
7. There is no vaccine or treatment for Zika virus infection.
8. The best way to prevent Zika virus infection is to avoid exposure to mosquitoes.
9. Pregnant women should take extra precautions to avoid mosquito bites, as Zika virus infection during pregnancy can cause serious birth defects.
10. Travelers to areas where Zika virus is circulating should take steps to protect themselves from mosquito bites.
