##### Across

**2.**Lines that are always the same distance apart, they never intersect**4.**A triangle whose all three sides are different, the sum of all the angles is always 180 degrees**7.**A type of triangle that has one of its angles equl to 90 degrees, the other angles sum up to 90 degrees**9.**A triangle that has all the sides equal, this triangle is simetric**10.**A line with just one endpoint, it extends infinitely in one side of it**11.**Lines that intersect, when they intersect they need to be 90 degrees**14.**Two equal angles, they measure exactly the same**16.**Angle that is equal to 180 degrees, it appears as a straight line**18.**Angle formed when two lines meet each other at a point**19.**Fragment of a line, it has two end points in each side of the fragment**20.**Angles that measure less than 90 degrees,they are smaller than right angles**21.**Angle that share a common vertex and a common side, they donĀ“t overlap

##### Down

**1.**Angle formed when the sum of two angles add up to 90 degrees, they need to be consecutive**3.**Segments that have the same length, the midpoint of a segment is the one that divides them**5.**Angles that measure exactly 90 degrees, you can find them anywhere**6.**Formed when two straight lines or rays meet, it has a common point of contact**8.**Angle formed when the sum of two angles add up to 180 degrees, they need to be consecutive**12.**A triangle that has two equal sides, the two sides have the same lenghts**13.**Angles that measure more than 90 degrees, they are bigger than a right angle**15.**A straight one-dimensional figure, extends endlessly in both directions**17.**A type of triangle that has all the angles acute, the three angles measure less than 90 degrees
