3. trisect means three
Three ! The answer is in the question !
An equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees and trisecting a 60 degree angle equally would give 3 equal 20 degree angles.
128 cuz 180 take away 55 is 128
An equilateral triangle on on of the arms of the right angle.
The complement of a 55 degree angle is a 35 degree angle
The angle opposite the 55 degree angle will also be 55 degrees. The other two angles will each measure 180 - 55 = 125 degrees.
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.
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
acute
3. trisect means three
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.)
That's an acute angle.
Three ! The answer is in the question !
55 degrees.
A pair of complementary angles sum up to 90 degrees. In this instance, the complement of a 55-degree angle is 90 - 55 = 35 degrees.
An angle measuring 55 degrees is an acute angle since it is measures less than 90 degrees.
