To trisect a right angle form an equilateral triangle with one vertex at the right angle and then bisect that angle of the equilateral triangle.
(It is impossible to trisect a general angle using only compass and straight edge - the right angle is a specific exception.)

To trisect an angle you first construct an equilateral triangle?
Right
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
How many degrees does a triangle third angle have?
it depends on the first two: angle3 = 180 - angle1 - angle2
In a triangle the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third angle is four times the measure of the second angle. If the total number?
Let the second angle be x degrees. The first angle would then be x + 24 degrees, and the third angle would be 4x degrees. According to the triangle angle sum theorem, the sum of all three angles in a triangle is 180 degrees. Therefore, you can set up the equation x + (x + 24) + 4x = 180 and solve for x to find the measures of all three angles.
In a triangle the second angle is twice the first angle and the third angle is 20 less than the first angle find the measure of all three angles?
Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o

Right
To trisect a right angle you first construct an triangle?
equilateral * * * * * * * No its right. Apex is stupid in ways no one can explain so yeah...
Is it true that to trisect a right angle you must first construct an equilateral triangle?
how many lines of symmetry does a regular polygon with 32 sides have
To construct a angle you first construct an equilateral triangle?
Yes
To trisect a what kind of angle you first construct an equilateral triangle?
Not too sure of the question but an equilateral triangle has 3 equal sides, 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
If I have an answer to the trisect any angle geometry question how can I discover if I am right or wrong?
First things first, the actual statement isn't "you can't trisect an angle" but rather "you can't trisect one with only a compass and straightedge." Some angles can be easily trisected--a 90-degree angle trisects into 30-degree segments-but to do it you need a protractor. Anyway, to check your work measure the angle you trisected and divide by three. If your trisections match, you got it right.
How do you construct an isosceles triangle when base and angle at the vertex is given?
First find 180 minus the vertex angle and divide that by 2 to get the other angles. Then solve the other sides by using sin(vertex angle)/base=sin(other angles)/other sides.
How do you find the first angle and the second angle of a triangle?
use a protractor
How would you construct an isosceles triangle if only given the vertex angle and the radius of the circumscribed circle?
You have an isosceles triangle, and a circle that is drawn around it. You know the vertex angle of the isosceles triangle, and you know the radius of the circle. If you use a compass and draw the circle according to its radius, you can begin your construction. First, draw a bisecting cord vertically down the middle. This bisects the circle, and it will also bisect your isosceles triangle. At the top of this cord will be the vertex of your isosceles triangle. Now is the time to work with the angle of the vertex. Take the given angle and divide it in two. Then take that resulting angle and, using your protractor, mark the angle from the point at the top of the cord you drew. Then draw in a line segment from the "vertex point" and extend it until it intersects the circle. This new cord represents one side of the isosceles triangle you wished to construct. Repeat the process on the other side of the vertical line you bisected the circle with. Lastly, draw in a line segment between the points where the two sides of your triangle intersect the circle, and that will be the base of your isosceles triangle.
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
Is it possible to construct angle 45 With the help of a ruler and a compass?
Yes. First draw a perpendicular (90 degrees) and then bisect the angle.
What will the measure of the second acute angle be if the first is 28?
If its a right angle triangle then the second acute angle is 62 degrees
