A triangle that has one of the three interior angles greater than 90 degrees is called an obtuse-angled triangle. Right Angle Triangle A triangle where one of the three sides is exactly 90 degrees is called a right-angled triangle. The side opposite to this 90-degree angle has the longest ...
Angle-Angle-Side (AAS):When two angles of one triangle are identical to two angles of another and one side of each of those triangles measures the same, you can bet they’re congruent. Hypotenuse-Leg (HL):This theorem only applies to right triangles, or those with one 90 degree angle. ...
We built four triangle houses with nothing more than a compass and a ruler. First, we made a congruent triangle. This involved copying the sides of the original. Next, we constructed a triangle based on two sides and an angle. Read Constructing Triangles: Types of Geometric Construction ...
Step 2: With the help of protractor and with A as center draw an angle of 45 and extend its arc to any convenient length, as shown below: Step 3: Now, again with the help of protractor and with B as center; draw an angles of 60 which intersects with arm of ∠ A at point C, ...

Learn that a right triangle has one 90-degree angle. The side opposite the 90-degree angle is the hypotenuse, and the other two sides are the legs of the triangle. The Pythagorean theorem relates to the right triangle and states that the square on the hypotenuse is equal to the sum of ...
eld of degree at least two, then one can apply the so-called elliptic Chabauty method (see [2, 3] and the references given there) to determine all solutions with the required property. 2. curves defined over Q 2.1. (α, β) = (π/3, π/2). The system of equations in this ...
First we read "The degree measure of a base angle", so let's start with X=Our equation so far: X=Now we see "exceeds three times... Y... by 60", which means 3Y + 60.Our equation now: X = 3Y + 60Since we know that X = Z because it is an isosceles triangle, then we ...
30°- and60°-Angle Values (from a30-60-90triangle) When we need to work with a30- or a60-degree angle, the process is similar to the above, but the set-up is a bit longer. (A30°angle is equivalent to an angle ofradians; a60°angle is equivalent to an angle ofradians.) ...
